Make the debugger mobile-compatible

[Gama11]

Probably disable the console for mobile targets.

Add the option to toggle individual debugger windows - for debugging on mobile targets, you might only want the Perf window for example.

The debugger would also need a button for closing, because you can't really close it via a keypress on mobile targets. This should combo well with the custom debugger buttons: #348

This can be really useful because right now the debugger is really hard to use on mobile.
