This change fixes two major issues:
1. If you don't use SIGQUIT to stop Plex it will corrupt its own
database :(
2. Newer versions of Plex keep metadata in the
`com.plexapp.plugins.library.db` database. This is the file that
we copy into `/var/lib/plex/.skeleton`. If we copy the empty
database on top of this one the user will lose their entire
library metadata. This change skips the copy if the file
already exists.
We don't want to build all those things along with the manual, so that's
what the defaultText attribute is for.
Unfortunately a few of them were missing, so let's add them.

Added support for managing Plex plugins via Nix. This is done via an
"extraPlugins" configuration option which takes a list of paths to
plugin bundles, which are then symlinked into Plex's plugin directory
when the service is started.
