Import original simpleid source code, release 0.8.4 from http://simpleid.koinic.net.
Remove version control cruft from licenses and rename them to something more appropriate.
Miscallaneous style changes.

1. Rename all .inc files to .php (honestly, why?)
2. Fix original author attribution in license (no name was specified?)
3. Remove excessive license comments from nearly every php file except where multiple attributions are present. Todo?
4. Reorganize directories (this probably breaks things, to be fixed)
