This should fix up potential locking issues with maintaining a copy of
the results set while certain other background actions may happen, such
as the player updating play counts while playing.

Apparently we need this to prevent Core Data from stomping on itself
when another thread accesses it.

Refine the global variable usage, eliminating double underscore prefixes
and trusting that static global variables will exist in the object where
the class was created. Got rid of that nasty NSApplication extension
hack that was previously in use.

Handle missing track items in the databse more gracefully, by deleting
the track entries before passing them on to the caller, so problems do
not occur later.

Completely rewrite the playlist storage once again, this time with a
much faster Core Data implementation. It still uses a little magic for
Album Artwork consolidation, but string consolidation doesn't seem to be
needed to reduce the disk storage size. Works much faster than my silly
implementation, too.
Old implementations are still kept for backwards compatibility with
existing playlists.

Every schema upgrade process should fall through to the next highest
version number, so they should all run, if the user has somehow upgraded
their database from such an old version.

Various warnings related to uninitialized variables, or setting values
to variables that would not be used later or would be overwritten by per
loop initializers.

String and art adder functions now perform type checks, in case of
memory errors that somehow result in classes changing type. Which in
itself is a strange thing to happen.

Restructure the add string or art functions so they don't take a pointer
to a pointer, which may have caused issues when receiving a nil string
from the caller. Instead, take a plain pointer, and return the object,
returning the ID of the object to a pointer to an int64_t.
Also change several prototypes and functions to use _Nonnull or
_Nullable where appropriate.

Artwork deduplication should be done with hashes, not by full data
comparison. This should be a lot faster loading artwork from files now,
especially if the playlist already contains a lot of unique artwork.

Strings read from the database were not being stashed in the memory
store, which caused things like blank tags instead of correct metadata.

Added a string dictionary for deduplication of metadata, and actually
initialize both it and the art dictionary on startup, so they actually
work like they should.

Art ID should be set on new files when they are stored into the
database, and the album art property should be affected by assigning to
the artId property, since it affects the caching identifier.

Now cache around NSData objects of individual pieces of album art,
unique by their byte contents. And the artwork image cacher will also
use the art ID keys from the database as the cache keys for NSImages,
so they'll not only be only read once per unique image, but also tracks
can have unique artwork per track, if the files so feature it.

Track entries are updated when files are added and their metadata is
later loaded. The refresh cycle was failing, because dbIndex was unset
in the new tracks, for some reason. Now it will set this when updating
the track item, assuming it read from the database in the first place.
This fixes metadata being loaded properly on adding tracks to the
playlist, as well as reloading track data manually.
Fixes#218, hopefully.

- Display playlist total duration in units up to weeks and down to just seconds, and only pluralize units as necessary
- Major change: Implemented a SQLite disk backed playlist, track data, and queue storage system, which will be synchronized from the player in real time, and will hopefully survive system or app crashes. Existing plist playlist will be imported on first run, and removed on shutdown.
