Merge branch 'issues-filters' into 'master'

Big refactoring of issues filters

* No magic numbers for issues filtering
* Squash project users selectbox and users selectbox into one class
* Move from API autocomplete to GitLab internal one
* Smarter filter for project/group/all issues
* Use selectbox with searchbox for assignee/author/milestone/label
* Switch to ajax filter for issue author/assignee

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/1035

See merge request !466
