I hope this fixes Jenkins!

Evan Polekoff
Ok, now it should really fix Jenkins.

Fixed Jenkins.
Merge branch 'team1-gui-adjustments' into team1-dev
cleaned up the code for the buttons, for iteration and Requirements
Added authors to RequirementPanel- Ned Shelton
Merge branch 'team1-dev' of https://github.com/cmdunkers/wpi-suite-tng into team1-dev
fixed the resizing issue for the requirements panel
When you enter an estimate now, you no longer need to hit enter to make the iteration dropdown editable. Simply typing a number will do it. I also fixed an exception that was thrown if you hit enter on an invalid estimate.
I also added documentation to the code Ned and I wrote for iteration 2. It looked confusing, so I label what everything did.
