Add loop speed constant.
Edit comments.
Rename BillboardGui lookup table.
Use a variable to store if the camera is in range.
Put the loop for connecting buttons in GameLogic.

Turns out this was generating an obscene amount of BillboardGuis inside
of the buttons when ConnectNewButtons was being run.

Putting the loop inside of the initialization function should fix that.

Now I'm wondering if there's anything else I've messed up this badly...
Add a form of garbage collection for the BillboardGuis.
Rename Billboards to BillboardHandler.
Give newBillboard an optional 'name' parameter.
Add method to set initial Tycoon values.
Add comments to GameLogic.
Add groupDigits function.
