[engine]#67 Add support for touches API in SDL, exposed in IND_Input in a very basic manner. Also added keyboard focus API for devices with on-screen keyboard

Changed tests to begin/end keyboard focus (shows onscreen keyboard on iOS), and also Q,E keys rotate screen instead of mouse button.

Also key up 'M' and 'N' change tests, instead of arrow keys
Rename resources directory to 'assets', as it made conflict on copy phase with XCode with previous name. Fixes app not running on iOS debugger, nor resources loading properly from bundle
