Preset UX Smoothing

[glipR]

Rather than having saved sim files, what will be much more intuitive is just having saved settings / bots for each preset type.

So there is a single .sim file for soccer/rescue, and then from the users perspective they just hit Soccer -> Accept Current Soccer Settings -> Accept Current Soccer Bots -> Play. I'd also add a quickstart button from the simulate menu to avoid accepting settings/bots.

This should also include an overhaul of the bot selector menu, as it is the clunkiest menu on the sim atm.
