Add example on how to use the mouse

[tehKaiN]

Is there any example of how to use a mouse?

I'm looking at Open Fire's code. I've copied cursor.c, cursor.h and cursor.bm to my project and then I included the cursorCreate, cursorUpdate and cursorDestroy calls but nothing happens.

Maybe I missed something related to the Copper. Anyway it would be good to have an example of a mouse application in the showcase.

Todo:

• Code in showcase
• Tutorial in ACE's docs

I'm now looking at code from openFire and it should work, perhaps there's some kind of regression.

The absolute bare minimum to process a mouse should be:

• do a mouseCreate() / mouseDestroy() somewhere - on game create/destroy or gamestate create destroy or something
• between them do mouseSetBounds() at least once
• do a mouseProcess() periodically
• after above steps mouseGetX() and mouseGetY() should return current x/y position of a mouse
• then one can go crazy with rendering mouse cursor - it could be blitter based (blitRect, blitCopy, line drawing fns) or sprite based (there are no examples for using sprites!)

Now to do an example for that.
