This adds an Animation panel to the Mask tab of the n-panel of the Movie Clip and Image editors. Masks can be animated (for example, the opacity of a Mask Layer), but there was no way to manage the Action and Slot that held those F-Curves. To keep things DRY, this PR also moves the code for drawing Action+Slot selectors from the `PropertiesAnimationMixin` class to a utility function, which is now called from both that class and the Mask UI code.
