Shortcuts preference pane (#3641)

* Shortcuts preference pane

* Honor and glory to the hypnoclangifier

* clanfigy: exclude deleted files from being checked

* keep the olf translation context to be able to reuse old translations

* Fix gcc; extract translations

* Moved generic buttons after the groupbox

* Update current item on "clear/reset all"

* Sequenceedit: make buttons larger and translatable, add text

* Event filter

* Don't filter arrow keys; added placeholder text

* group counters
