Added 'Bulk edit' functionality.

This can be done by clicking on the edit link (little pen icon) at the upper-left corner of the issue list.
Most properties can be set (priority, assignee, category, fixed version, start and due dates, done ratio) and a note can be entered.
Only issues of the current project can be selected for bulk edit (subproject issues can't).
