Quite a few changes since the last commit, so bear(rawr) with me.  Finally included the chunk the the work, screen buffer.  The vhd file was built to meet the specifications of the diagram on the website that will be included in the report. Some problems encountered were determining what to tie to signals such as data_in, which I just tied to the binary value of A.  Most of the errors encountered were attempting to get all the inputs and outputs to be at the correct value.  Require functionality has been met, except for the hsync, vsync and vcompleted need to be pipelined so everything is on the correct clock signal.  Sorry this is all in one commit.  Code in the top shell was moved around for readability and the pixel gen commented out for testing purposes.  Not including the UCF file in the project stumped me for almost half an hour.  Next commits should be much more specific, as I move step by step.
