Don't let the RDP get too far ahead of the other cores or
it causes lots of frameskipping issues. Unfortunately, this
also hurts the performance but such is life.
CEN64 with -multithread now scales up to three threads.
This commit is very unoptimized, but still offers VI/s
faster than the single-threaded RDP.
Many things that were previously VI/s limited such as
Mario Tennis (in game), Vigilante 8, Goldeneye, etc.
will now run at 60 VI/s at least on an i7. More to come
in the future.
Replaced all references to simulation with emulation
Updated copyright year
Updated .gitignore to reduce chances of random files being uploaded to
the repo
Added .gitattributes to normalize all text files, and to ignore binary
files (which includes the logo and the NEC PDF)
