Anna Schumaker 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.

Anna Schumaker 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.

Anna Schumaker 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.
