Began adding basic authentication
Finished the server-side modifications (read more)

* There seems to be something iffy with this branch
* The size of SerialPacket may have changed

I've implemented the accountIndex variable as best I can, but I really
shouldn't code at night. I'll need to go over the changes again before
merging this.
Merge branch 'account'

Added the "accountIndex" variable to the SerialPacket.
Updated TODO, might as well merge this into the master
Merge branch 'database'

Conflicts:
	todo.txt

Merging todo.txt into the master branch, despite trying to keep it
separate.
