Adding message-max-length configuration directive in notifiers configuration
%project% tag is available in review request notification message pattern
Fix bug when multiple options were added to the git diff command
File lines must be displayed correctly whatever the file encoding is.

Symfony escaping is enabled and use htmlspecialchars internally (using sf_charset configuration directive to know the encoding)
The project is configure as UTF-8 project. Problems appear when lines of code to review are in another encoding (for example ISO-8859-1).
In that case, some lines can appear as empty.

The fix relies on encoding detection (at file level) to switch the sf_charset value (only to ISO-8859-1 for the moment).
