Add PanelState, PanelStyle and PanelType enums

The new _panelState tells if the panel is currently in the process
of being toggled between icon-style and text-style verbs and thus
animated.

The new _panelStyle tells wich verb-style the panel currently uses.

The new _panelType tells which mode the panel currently is in:
  - verbs + inventory (normal)
  - empty (used for dialogs)
  - save, load, play, quit buttons
  - save/load savegame

Also, switchPanelType() has been renamed to togglePanelStyle() and
kInputKeyToggleInventory to kInputKeyTogglePanelStyle to better
match the above changes.
_switchPanelFlag has been dropped in favor of using the new _panelState.

TODO: Store _panelStyle in savegames.
