Add a new format specifier "$q" to generate "queryable" (scrapable) names for recordings. This relies on good guide data, typically xmltv data that contains "movie".

This format specifier helps split movies and shows in to separate hierarchies without needing post-processing.

Examples are:
- tvmovies/Gladiator (2000)
- tvshows/Countdown/Countdown
- tvshows/Bones/Bones - S05E11 - The X in the Files

A couple of other modifiers are also added for cases where guide data is not good so recordings can be forced to be movie or tvshow for cases where a user has separate recording profiles for movies and shows.
