Automatically generate cache file

Browse source 
This makes updating cache files easier; you just delete the old one and try completing again.

# zsh completion for beets music library manager and MusicBrainz tagger: http://beets.radbox.org/
# NOTE: it will be very slow the first time you try to complete in a zsh shell (especially if you've enable many plugins)
# You can make it faster in future by creating a cached version:
# 1) perform a query completion with this file (_beet), e.g. do: beet list artist:"<TAB>
# to create the completion function (takes a few seconds)
# 2) save a copy of the completion function: which _beet > _beet_cached
# 3) save a copy of the query completion function: which _beet_query > _beet_query_cached
# 4) copy the contents of _beet_query_cached to the top of _beet_cached
# 5) copy and paste the _beet_field_values function from _beet to the top of _beet_cached
# 6) add the following line to the top of _beet_cached: #compdef beet
# 7) add the following line to the bottom of _beet_cached: _beet "$@"
# 8) save _beet_cached to your completions directory (e.g. /usr/share/zsh/functions/Completion)
# 9) add the following line to your .zshrc file: compdef _beet_cached beet
# You will need to repeat this proceedure each time you enable new plugins if you want them to complete properly.
# IMPORTANT: You need to change the $completionsdir variable defined below to point to the directory where your completion files
# are stored.
# It will be very slow the first time you try to complete in a zsh shell (especially if you've enable many plugins),
# but a cache file (_beet_cached) will be created after the first completion which will make subsequent calls much
# faster. If you enable new plugins or fields you should update the cache file by deleting it and then performing
# another completion in a new shell.
# If cache file exists, use that
