== Action Editor - Fixed 2 Long-Standing Annoyances ==

This commit fixes two long-standing annoyances which were confusing to new users and also posed workflow bottlenecks:

* A 'Fake-User' button is now displayed beside the delete button. This makes it clear to the user that actions have a fake user (by default), and provides quicker access to them when 'deleting'.
** Related to this, I've adjusted the tooltips for the fake-user button when there is a fake user, to clear up any ambiguity over the purpose of the button.

* When an object has an Ob-IPO (i.e. keyframing object transforms), it is now possible to simply use the 'Add New' entry in the Action Editor to make a new action for the object, with the IPO assigned to a new Action. This removes the need to open an IPO-window just to do that.
