tasksperuser: checkbox for in progress/all projects (part of #1552), rearrange checkbox/label (part of # 1536)
updated to allow task viewing based on system admin access as opposed to user admin access
Removed the "all users" option because it's a ridiculous thing to have here.. it hammers on the system unnecessarily

Merge pull request #259 from opto/stable3.2pre
