Beta 2: BUGS: Global vals, End App, button drawing

[Simon]

I noticed some issues:

* Global values/strings set at build time are not holding their values and initialise as 0/empty string.
* Setting a global string seems to be crashing the runtime
* End Application closes the joystick display, removes buttons but does not close the application canvas
* Buttons are being drawn on top of joystick controls

I have attached a small mfa, compare the behaviour in MMF and on the iPhone. This is running in the simulator as I don't yet have an iPhone. I used iOS 4.1 profile.

I narrowed it down to the string setting causing the crash, setting button alterable value and global value do not appear to cause the crash.

-> Global Values at init time : corrected
-> Setting global string : corrected (plus a bug in unicode)
-> Button drawing over joystick : I'm afraid this one is impossible to correct (buttons are drawn by the system)
