The majority of this work can be summarized as: Makefiles have been added to
generate all of the boards, boards for each vendor, board, and projects for each
board.
To make things cleaner I renamed a few of the Xilinx projects, and may rename
the latera projects for consistency.
I removed the de5_qsys directory, and moved all projects into the de5 directory,
but those projects have a Q between DE5 and the PCIe specifications, ie
DE5QGen... (haven't updated the documentation)
Added c4dev board (untested)
Apologies to those of you who recently switched onto the DEVEL branch.
