fixed up invalid print type after execution error
added some wrappers for omdb and tvdb

* adjusted util/retrieve function calls accordingly.
* removed get_id from util/retrieve.py and will soon remove the entire module.
all calls to tvdb will be done through util/apis/tvdb.py.
* completed the api wrapper for omdb and it should fully work.
* requests.get() requests now have a 10 second timeout.
* might change requests.get() to use post requests.
* renamed thetvdb.py to tvdb.py
moved imports around to make it more clear
should add an option for default timeout
