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.

a5891a3338 database: Implement quick removal of items
Items will be marked "invalid" rather than directly removed from the
database.  This make it easier, since I won't need to reassign IDs to
every database item after the removed one.

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.

I don't have the DatabaseEntry base class yet, but I will soon!
