Merge lp:~brandontschaefer/mir/lp-1252498-fix into lp:mir

[Brandon Schaefer]

Adds support to the MirMotionEvent under pointer_coordinates called tool_type. This will allow clients to tell what type of tool is being used, from mouse/finger/etc.

The mir event api does not expose what type of tool is for each pointer_cord. Some toolkits need to know the difference between different types of tools.

Adds a new type to pointer_cords, removing an 'int unused' and replacing it with an enum MirMotionToolType.

Adds tests for single pointer events, and multiple.

looks okay to me

Interesting that we explicitly support multiple simultaneous tools touching the screen :)

I actually came up with a need for this myself yesterday, so thanks.
