Update files to v13 (most recent production files)
Update tree to SparkFun standard
Mods for threaded inserts, PTH battery holder.
- Modified .sch and .brd files to V13 to add PTH battery holder.
- Modified enclosure file to change thickness of layer 1 and hole
   sizes on layer 1 to 3.9mm.
Tweaks to board, enclosure, repo
- Enclosure:
 * Hole size in layer 1 is now right for threaded inserts
 * Change thickness note on layers 2 and 3 to 1/8"
 * Moved lever from center of layer 3 to ensure thickness of plastic would be the same
- Board:
 * Tweak battery holder down slightly, as it was interfering with display
 * Change to rev 15
- Repo: move enclosure file to top level, per SparkFun standards
Modified enclosure so PTH batt holder fits
Bring the new stuff for the V3 BigTime in.
