Broken 600D & edmac_memcpy

[dslrrookie2]

Following Alex's recommendation on the channels in edmac_memcpy, I used 4 for writing and 19 for reading, I compiled a build and so far so good.  Some testing with RAW and MLV to compare pink frame issues ... seems about the same, needs more testing.

Had issues getting the build to complete with rst2html errors ... solved by installing docutils.
