Increased support for seeding torrents after rename.

Instead of simply leaving an option to keep files when renaming, there are now four options.
Move - Do not keep just move.
Copy - Same as keep before, copy file.
Physical Link - Creates a physical link in the destination folder.
Symbolic Link - Moves the file and creates a link in its original location.

Combining post processing scripts with this will allow using to continue seeding torrents while still having the media files renamed/moved into their TV directories.

I've added linktastic to libs which is used by CouchPotato and nzbToMedia to create symbolic/hard links on both *Nix and Windows systems.
