Added DMA Test cores
Removed RAM initialization file load
Changed the behavior of the membase default base

Now instead of loading a default base address from within the module it
requires the instantiating module to set the default base size. This is
better because each implimentation of the DMA controller is unique and
requires it's own size requirements
Superficial change in spacing
Superficial spacing changes
Adapted the DMA Writer for with the new base behavior

Now the wb_sf_camera core sets the default base at startup
Initial commit of DMA Reader

This core can be used to test and benchmark DMA Reading and this will be
used as a template for a DMA reader core in the future
Changed the behavior the reset signal
Superficial change to the LCD Defines file
Added comment about possibly moving PPFIFO
Added save file for waveforms
Initial commit of DMA Writer

This core is going to be used to test/benchmark DMA Writer and will
serve as possibly a future template for designs
