updated import statements of all modules to reflect new hierarchy

as genomepy is now installed as a package, all import statements
for modules contained in the new package had to be updated. For
example:

import genematch

has now become:

from genomepy import genematch
updated config file path list and module access

Additional file paths were found in modules that needed to be
added to the config file, so the config script was modified
to find these files too, and the modules adjusted to now use
the config file pathways.
