Add ability to move files

[jhotmann]

Currently when you use rename, it will always keep the file in the same directory. Add ability to move files as well and an option to turn off file moving.

• Add ability to move files
• Add option --nomove to prevent moving files
• Don't fail if directory doesn't exist (maybe add to conflicts?)
• Prompt if directory doesn't exist and prompt or verbose options are passed
• Create directories automatically if force option passed
• Add option --createdirs to automatically create directories
• Warn if --nomove and --createdirs passed at the same time if verbose option passed
