Don't send notifications to mentioned users that don't have access to the project in question.

Fixes #1651

workaround for buggy lexers

It seems that some lexers can be buggy when used together with git blame.
This results in a 500 error when a user tries to open the blame page in some cases.
The workaround is pretty simple. Not only fall back to plaintext when the file content can't be guessed, but also when the lexer fails.

This closes #1521 and #1646

/cc @DouweM @JobV It would be awesome to have this in a patch release for 7.11 or even in the release. But that's probably to late.

Fix reference links in dashboard activity and ATOM feeds.

References like `@user` were not linked on the dashboard activity feed and in Atom feeds, because the reference parser depends on `@project` which isn't set in those situations.

This MR passes the project in question to the reference parsers in an option.

Protect OmniAuth request phase against CSRF.

Addresses #2268.

See merge request !1793

Fix mentioning of private groups.

`issue.participants` would mistakenly not send the `current_user` to `mentioned_users`, which means it would search for referenced groups and users as if the user was signed out. Since signed out users don't have access to private groups (groups without public projects) and since you can't reference a group you don't have access to (since this would leak its existence), the group reference wasn't found and the group members weren't notified.

Addresses internal issue https://dev.gitlab.org/gitlab/gitlabhq/issues/2326.

Always show note action icons.

As discussed in #639.

The delete icon becomes red on hover, the edit one becomes slightly darker.

The "Link here" icon has been removed, and the link to the specific comment can now be found by clicking the post date ("3 months ago"), which is most other sites do it as well.
