Small change to timing of read_fifo.
Clean up user_logic and main.c to use only 3 register inputs.
Add NUM_BYTES_PER_PIXEL parameter to hdmi_core and update testbenches, user_logic.v
Fixed param passing in hdmi_out.vhd which propagates to user_logic.v.
RGB565 works now! Need to change the HDMI_BYTES_PER_PIXEL param in the MHS files or the XPS GUI in order to enable it.
Software changes in 565 mode are an attempt to mirror the exact image of the 888 software, albeit with loss in quality (because of loss of color).
Merge branch 'master' into bryce_25mhz
