uiabridge was having issues with getting ValueProperty from the cached
values. uiabridge was throwing exceptions if it couldn't find a missing
HWND handle. Fixing keyboard hook to last longer.
uiabridge will display ValueProperty if element supports it.
if uiabridge is disabled in synthuse.properties the native library will
not be loaded.
Added Trigger hot key Ctrl+Shift+`
Added hotkey configurations in synthuse.properties
