Modified behavior of -M and -E to allow multiple directories in priority order
Also modified config file support to follow suit
Update to extend base_dir to allow a prioritized list (same as previous change to -M and -E)
Also, version bump to 4.1
Updated grammar to better parse strings
Forgot to include quotes (" and ') in regex for string. Also changed quoted strings a bit so they
could more easily modified to add escapes if the need arises in the future
