* Moved some actions to match the file organization: actions are in the order they appear on a qwerty keyboard
* Removed actions for F1 and F2, these were hiding View actions
* Removed action H for hide, which was conflicting with play-selected-regions
* Moved the grouping of jump-to-mark actions into Moving the Playhead
This allows common keyboard shortcuts from any Tab (Editor, Mixer).
Discuss: should those actions/methods also be moved to ArdourUI instead of
PublicEditor?
This will work the same as the existing binding with a Region Selection and
will also duplicate ranges in range selection mode.
Also add multi-duplicate editor action and use that for the default
multi-duplicate action, which will work the same in Object Selection/Grab Mode
but also supports Multi Duplicate of Range Selections....well it would if
that functionality worked correctly.
The duplicate and duplicate-multi region actions still have to exist to be used
in the Region menu as they should only be sensitive if there is a Region
selection which would not be the case if the editor actions were used.
