fix blank episode titles, no playable streams foun

- Fix for blank episode titles. 
The meta info from metaget.get_episode_meta() function is often empty. If the title is blank it is replaced by the vidname.
- urlresolver: no playable streams found.
When the episode title has special chars these are not escaped before it is used in a regular expression search for streams. This results in no streams found. Added title escaping.
- Missing latestmovies with special chars in the title.
See above urlresolver: no playable streams found.
