Added brick graphics. Also started to add brick logic into the game but it's not yet implemented.

Work in progress is:
- brick control graphics.
- ball vs brick hit logic.

Compilation tests successful (@ Symphony EDA Sonata 3.0) but may experience some buggy behavior if trying to test on a live board because of the unimplemented mechanics.
