Exposed `get_focus_mode()` to the script
Added `focus_mode` to the property panels for line-edit and sliders
Added `enabled_focus_mode` to the property panels for buttons
enabled_focus_mode is used when button is enabled/disabled
A general speedup should be apparent, with even more peformance increase when compiling optimized.
WARNING: Tested and it seems to work, but if something breaks, please report.
