Remove unnecessary [] from season & episode regex
Use consistent names when talking about the episode name

Avoid the title/name split.
Rename library variable on TvRenamr to lookup

Avoid reassigning the library variable in TvRenamr.retrieve_episode_name
and assign to the TvRenamr instance again so it can be used in
TvRenamr.format_show_name.
Use title instead of name for episode

Avoid use of the variable `name` at all costs so it can't be confused
with `show_name`.
