Especially with Multi-Episodes, the EpisodeTitle can become quite long,
since all comprised titles get concatenated into it.
By default, the EpisodeTitle is included in the single and multi-episode
naming patterns and this in turn can quickly lead to a
PathTooLongException.
This fix tries to keep as much as possible from the title string while
keeping the final path within the allowed limit.
