f7a7710482 design: Rename a few subsystems
- Playlist -> playqueue.  Playqueue sounds more temporary, which better
  represents how I intend this code to be used.
- Groups -> playlist.  A playlist is the accepted term for what I am
  trying to create here.

31e6bcef3b design: Modifications needed by the GUI
This patch writes out various modifications the GUI will require the
back-end library to make.  This includes:

- Rename playlists to playqueues and groups to playlists.
- Make library information accessable.
- Use try/catch style errors instead of returning bool in a few places.
- Extra playqueue accessablity functions.

97d889531a index: Remove the index class
This patch updates the design so indexes are built upon databases using
a special IndexEntry.  I also updated the tests/index/ test to match
the new system, but I have not updated filter or group tests yet.

c2bc99ad9b design: Design out the index class
I made a few modifications to the database, and introduced an
"IndexEntry" database type to do the exact same thing :)

8ccbad20cc database: Mark rows valid when inserted
It doesn't make sense to need to set this value outside of the database
code like I had been doing.  So when a new row is inserted mark it as
valid right away.

79d592ed64 database: Add a function for printing
Other tests may need to print out a database.  To make this easier I've
added a print() function to the base database class.  This function will
only exist when CONFIG.TEST == True, so don't use it outside of testing!

dd92ee853f database: Add a way for databases to have unique keys
The library will need databases that have unique values (such as the
artist or album tables).  This patch adds support for that in my
existing database code.

13313482d4 database: Make read() and write() functions for database entries
I had planned on using the stream operator for my database class but
this created some crazy compiler error that I was having difficulty
figuring out.  I decided to take the easy route for now and instead
create read() and write() functions that do exactly the same thing.

50a7c3dae6 database: Add funcions for database iteration
A database may have invalid rows.  If this is the case, then the next()
function needs to return the id of the next valid row.  I'm aware that
this could get horribly inefficient on large DBs with many invalid rows.
I don't expect people to delete large chunks of music all at once, but a
defragment tool is on my "todo" list for a future Ocarina version.

fee08b1f94 database: Begin database code
I've been excited about this!  I think it'll be a better design than
what I had for Ocarina 5.x.

e13b4afa60 design: Break doc into pieces
Each component has its own text file.  I merge everything together with
simple dependency resolution so I can figure out implementation order
easier.
