Add tags relevant to classical music.

This commit adds some tags that are (mostly) interesting for listeners of classical music. Ensemble -------- This is an ensemble that is playing the music, such as Wiener Philharmoniker. The tag can be used to distinguish the ensemble from the conductor, composer, soloist, and ensemble, that are generally all in the "ARTIST" tag. Movement ------- The movement number and movement (name) of this track, i.e. "II" and "Allegro". ComposerSort ------------ Allows us to look for Beethoven's 9th under B, for Beethoven, not L for Ludwig. Location -------- This is the location of the recording, e.g. "Wiener Musikverein".

Add tags relevant to classical music.
