Another phase in panelizing all window types. Did lots of small code

fixes, including:

- Panel in action window (disabled it, since there's no need for it)
- fix: when action was added to mesh with vertex keys, the action couldn't
  be deleted, nor did action window draw key names
- mouse on RVK (key) in Action window: Nkey menu pops as well.
  This is not a good candidate to put in Panel, no selection possible here.
- when you change name of RVK in action window, it shows in IpoWindow too
