This patch accomplishes a couple things:
- The actions on the timeline header can now be assigned to shortcuts.
- Refactored the action docker actions to use the same createAction pattern that other actions are using (removed a todo)
- The KisAction class can now change its display text. This is needed for a timeline header action where the text changes depending on how many frames you have selected.
We are currently calling a few of these action names "columns", but I wonder if we should change the name to "frames" or something more consistent with the rest of our terminology?
