Vkeybd: grab all key-events and use timer instead of key-repeat

This fixes an issue with arrow-keys (up/down, left/right). Those
were previously only handled when the Virtual Keyboard window itself
had focus.

Also key-repeat for pitch-bend is now ignored and a dedicated timer
is used to queue events. This fixes an issue with the first repeat
taking longer than successive ones, and makes this feature independent
of any desktop user settings.
