Commit message

Support animated cursors

Description of the change

* Are there any related MPs required for this MP to build/function as expected? Please list.
https://code.launchpad.net/~dandrader/unity-api/removeHotspot/+merge/293627
https://code.launchpad.net/~dandrader/qtmir/removeHotspot/+merge/293629

* Did you perform an exploratory manual test run of your code change and any related functionality?
Yes.
For testing you have two options:
1 - Run "make tryCursor". Then type "watch" in the cursorName field and hit the "Apply" button.

2 - Run the demo app:
- bzr branch lp:~dandrader/+junk/animatedDemos
- cd animatedDemos/CustomCursor
- qmake && make
- cd ..
- qmlscene CursorShapes.qml -I . --desktop_file_hint=unity8
- hover mouse over the "Wait" or "Busy" boxes as they are the only ones with animated cursors.

* If you changed the packaging (debian), did you subscribe the ubuntu-unity team to this MP?
Not applicable

* If you changed the UI, has there been a design review?
Not applicable

Arguably, you should probably bump the Cursor plugin version to 1.1 (in qmldir and plugin.cpp) as this is not backwards compatible.
