Outliner RMB Menu - AnimData mangement

* When clicking on "Animation" items in the Outliner, there's now a
menu containing from which you can change the action used, and
refresh/delete all drivers.

* Moved action-setting logic for AnimData actions to a single utility
function in anim_sys, since this was starting to be done in too many
places already.

* Fixed Outliner refresh bug after changing the active action
