emblem core functionality

==What's needed==
1) departure's set of emblems
What's probably going to end up happening is the following:
 * I'm going to want to use it in other themes, and for it to take off, it has
 to work with other themes as well.
 
 * I'm going to end up making the emblem system separate from departure and
 instead have it be called from the main SM directory.

Skip all of that and get the basics down first.

2) I need to have a way to relate song/group/course names and banners
My idea I guess is to have a table object storing the a few things.

Title and Filename are going to be in each, but we also need to account for
the way people name things. if we do a search for specified terms for specific
folder names, we can do good.
