I have to domesticate RubyMine, keymapping is not the same as IntelliJ and I have deleted a character by mistake...

2/ @commit.safe_message as an argument
3/ preserve in helper
4/ spaces around operators

It matches #[0-9]+ in commit messages.
For example
 * Fix for #12
 * Code review for #56
 * Test for #15, Review on #54, Fix for #42

 It only links to valid issues (existing and belonging to the current project)
 It does not add any link to the commit in the issue page, it only consists in parsing the commit message when displayed.

 This can be considere as a primary work for the issue #155 on gitlabhq/gitlabhq.

Alert only commit author on note

Added missing link to favicon

Allows to alert only the commit author when a new note is added on a commit, useful when gitlabhq is used for code
reviews, allows less noise with mails...
