Fix to make new console + behavior editor working
Integrated NUI framework to be available ingame.
Fixed integration of ingame NUI
 - Mouse now correctly grabbed and released
 - Axis inputs now correctly consumed
 - Focus now correctly lost when an widget isn't rendered.
Fixed support for releasing the mouse with F1.
Removed old console.
Fixed slider min size
If a bind is triggered by a consumed input, it no longer repeats.
NUI will now consume binds when a mouse releasing screen is open.
Console's command entry box will no longer lose focus - widgets can now set whether they can be focused on or not.
Escape can now be used to close screen layers, if they don't disable this feature.
Merge remote-tracking branch 'upstream/develop' into behavior
