Issue tracker

This includes commits from Sarup's redesign branch. 

Issues are now labeled with IDs **respective** to their project. I.e. the first issue on a project appears as **# 1** and not the default id value set by Rails. Also, you can now close issues and filter the issues view to show only open or only closed issues.
