New menu system

[thelusiv]

In SVN r992 all the "stuff to add" from 2 posts ago is fixed, except for a way to change to and calibrate the next joystick(s). Actually, the way it works now, if there are two joysticks being calibrated at the same time, it will draw one joystick's set of axis grids on top of the other one. I plan to add a wheel widget that lists all available joysticks and switches the calibration grids between then when changed. The only other thing mentioned as needed 2 posts ago was some some visualization or something of the deadzone, but I'm going to hold off on this one, because I realized it's a lot more complex than I thought... :?

Also I fixed the bug that only allowed the first three controls in a controlgrab to be clicked on. Now the clickable area is extended to fit any number of controls.

gui todo list
* replays (record/play)
* text overlay for controlgrab icons
* textbox voodoo magic
* control double-assignments...
* prettier multiple joystick calibration

p.s. no I don't plan to implement car parts yet, I want to wait until the new game world/player system is set up...
