Class Swap Helper

Not much has changed besides some very minor re-arranging of some code, and the addition of meta data added to the .toc file.

This was bumped to v0.2 mainly because I believe it's been tested enough to call it beta. The other reason is because curse.com won't show any files if you call it "alpha" ;P

- If your character has two classes, but you set one class to  "none", then the swap button won't work until you change it two show two characters and use the original Confirm button.  The reason is because the addon only tests that you have a sub class when the Class Change window first appears.  This may be fixed in the future.

- If you cancel the changing of your class when it asks you to confirm, then the pressing the swap button won't switch them again.
