As recognised in #21841 the rendering of plain text files is somewhat
incorrect when there are ambiguous characters as the html code is double
escaped. In fact there are several more problems here.
We have a residual isRenderedHTML which is actually simply escaping the
file - not rendering it. This is badly named and gives the wrong
impression.
There is also unusual behaviour whether the file is called a Readme or
not and there is no way to get to the source code if the file is called
README.
In reality what should happen is different depending on whether the file
is being rendered a README at the bottom of the directory view or not.
1. If it is rendered as a README on a directory - it should simply be
escaped and rendered as `<pre>` text.
2. If it is rendered as a file then it should be rendered as source
code.
This PR therefore does:
1. Rename IsRenderedHTML to IsPlainText
2. Readme files rendered at the bottom of the directory are rendered
without line numbers
3. Otherwise plain text files are rendered as source code.

The real sensitivity of ambiguous characters is in source code -
therefore warning about them in rendered pages causes too many warnings.
Therefore simply remove the warning on rendered pages.
The escape button will remain available and it is present on the view
source page.

This PR rewrites the invisible unicode detection algorithm to more
closely match that of the Monaco editor on the system. It provides a
technique for detecting ambiguous characters and relaxes the detection
of combining marks.
Control characters are in addition detected as invisible in this
implementation whereas they are not on monaco but this is related to
font issues.

Previous solution that re-purposed the 'hide' class by making it
`!important` had various unintended side-effects where jQuery .show() was
not able to outweight it. Use a separate class to prevent these
interactions.
* Refactor `i18n` to `locale`
- Currently we're using the `i18n` variable naming for the `locale`
struct. This contains locale's specific information and cannot be used
for general i18n purpose, therefore refactoring it to `locale` makes
more sense.
- Ref: https://github.com/go-gitea/gitea/pull/20096#discussion_r906699200
* Update routers/install/install.go
- File headers can become quite width, so ensure the file size is not
being wrapped into itself(width + padding-right) and allow the overflow
to be scrolled(overflow-x).
Fix #17514
Given the comments I've adjusted this somewhat. The numbers of characters detected are increased and include things like the use of U+300 to make à instead of à and non-breaking spaces.
There is a button which can be used to escape the content to show it.

This extra whitespace caused isses in Firefox where it would copy a
extra space character at the start and the end. Additionally, in Chrome,
the text selection indicated a spaced on the end of the selection where
there was none. Both issues are fixed with the removal of whitespace.
* Cleanup and use global style on popups
- Fix typo 'poping' to 'popping'
- Remove most inline 'data-variation' attributes
- Initialize all popups with 'inverted tiny' variation
* misc tweaks
* rename to .tooltip, use jQuery

There are multiple places where Gitea does not properly escape URLs that it is building and there are multiple places where it builds urls when there is already a simpler function available to use this.
This is an extensive PR attempting to fix these issues.
1. The first commit in this PR looks through all href, src and links in the Gitea codebase and has attempted to catch all the places where there is potentially incomplete escaping.
2. Whilst doing this we will prefer to use functions that create URLs over recreating them by hand.
3. All uses of strings should be directly escaped - even if they are not currently expected to contain escaping characters. The main benefit to doing this will be that we can consider relaxing the constraints on user names and reponames in future.
4. The next commit looks at escaping in the wiki and re-considers the urls that are used there. Using the improved escaping here wiki files containing '/'. (This implementation will currently still place all of the wiki files the root directory of the repo but this would not be difficult to change.)
5. The title generation in feeds is now properly escaped.
6. EscapePound is no longer needed - urls should be PathEscaped / QueryEscaped as necessary but then re-escaped with Escape when creating html with locales Signed-off-by: Andrew Thornton <art27@cantab.net>

- Limit SVG images to 600px width

* Enforce tab indendation in templates
This adds editorconfig-checker [1] to lint the template files so they
conform the editorconfig files. I fixed all current identation issues
using the fix mode of eclint [2] and some manual corrections.
We can extend this linting to other files later, for now I'd like this
PR to focus on HTML template files only.
