add --no-repeat option for bindings

Browse source 
This allows e.g. triggering one command while a key is held, then
triggering another to undo the change performed by it afterwards. One
use case for this is triggering push-to-talk functionality for VoIP
tools without granting them full access to all input events.

Fixes #3151

define bindings which will be exempt from pass-through to such
software. The same preference logic as for _--locked_ applies.
Unless the flag _--no-repeat_ is set, the command will be run
repeatedly when the key is held, according to the repeat
settings specified in the input configuration.
Bindings to keysyms are layout-dependent. This can be changed with the
_--to-code_ flag. In this case, the keysyms will be translated into the
corresponding keycodes in the first configured layout.
