Renamed variables and commented code for readability

Renamed panes and variables so that the names were relevant (instead of panel_1, panel_2, etc.). The new variable names should help to make the code self-documenting. Comments were also added to help distinguish which areas of code corresponded with which panes.
Merge pull request #29 from sfmailand/sbl-dev

Add functionality to the 'New Game' button in the toolbar panel.

So this is great, but I feel like Austin's interface that he used in the Overview tab would make sense in the new game panel, and a Requirement's Manager like list of games would be in the Overview tab.  Then we could have a small bar on the right with the options to fill out for making a new game or something.
