Make the dict file conform with the back-end string parsing...  Originally
the back-end was never supposed to use those files, but now the wav file
pool is going to use it...

This does break backwards compatibility with previous PyDAWv3 project
formats...
Got everything compiling...  I won't bother running it because I know it
will SEGFAULT, but the only thing left to do is get the wav file pool
working, and everything should work...  Then the only thing left to do
on this feature branch is moving audio items to the region scope...
