Continued work on Acceptance Tests. Can now type in a test and hit "Add Test"
where the test will be saved to the requirement. This test will only stick
if the requirement is then saved.

Updated the Acceptance Test UI. Can not view list of tests and click on
a test to vie it's title and body.

merged in the fixes for the requirement panel, have been working on testing
Fixed the hack for getting iterations.
Axises for graphs only show integers.
Stacked Bar Chart works for Priority for all 3 things it can show. I need to add a new ComboBox to change it to Type.
tried to test, swithed up a few things for the requirements panel to make it easier to test
The button on the toolbar just says Chart now.
Added permission checking to AcceptanceTest view

Re-arranged GUI for AcceptanceTest view

More refactoring. Maybe it actually works.
