Added file globs to deb and rpm packager. Since the destination for
a glob can not be a single file, the files collected by the glob are
stored in: join(dst, trim(lcp(src), src)) (read: lcp = longest common
prefix). Thereby the longest common prefix is removed from every path in
the globbed files and joined with the destination path. Implementation
is backwards compatible (i.e. non-globs will work as before)
