Implemented tv filing process.

This creates the season directory and renames the file from the season and episode number. It does not actually move the file, as the rename command is commented out. This will be added when there is a 'dry-run' command implemented in the next commit.
Implemented dry-run argument.

This allows the program to run through, but not actually perform any actions. This can be used on any unknown filename format to make sure the program will work as expected.

This commit also uncomments the rename command, so upon determining the season and episode number, the file will be moved to its ultimate destination.
Advance to version 0.5

This also replaces the destinations with the actual values to be used in production.
