add: use advise function to display hints 

Use the advise function in advice.c to display hints to the users, as
it provides a neat and a standard format for hint messages, i.e: the
text is colored in yellow and the line starts by the word "hint:".

Also this will enable us to control the messages using advice.*
configuration variables.
