Fix warnings in C file.
First revision of RGB565 in hdmi_core.v
Fixed small typo in hdmi_core from previous commit. Simulation seems to show correct muxing of colors.
Software changes for 565 test. UG Machines went offline a few minutes ago so I can't test on board :(
Fixed mistake with read_fifo logic in hdmi_core.v
Paramterized fill_fifo_fsm and propagated parameters in user_logic.
More software changes for testing RGB565.
Set up user_logic.v to use 565. Doesn't actually work, output image is incorrect.
Merge branch 'master' into bryce_25mhz
