Clear files from directory by age

Looping through all directories and files in a directory.

Directories are checked for video files. If found these are moved to the base directory and the directory, and any other files inside is then removed.

Files in base directory are checked for age and removed if older than 90 days.

Update 2014-06-20:
* Added control if we got a directory.
* Added simpler check if we could reach supplied directory or not.
* Removed deluge-console check as it would sometimes hang and wasn't very useful to begin with.
