Cleaned up handling of various file paths throughtout the codebase. 

Basically, directories are now guaranteed to always end in the path
separator.  Ensuring this makes certain sections of code work faster,
and guaranteeing it allows higher layers of code to not worry about it.

Added 'cfgdir' commandline argument, to specify the default directory
for Distella-like Stella-compatible config files.

Implemented 'loadconfig' debugger prompt command.  It's currently
working great with several test config files provided by Omega of
AtariAge.
