STLBBS migrated to PI 2

In the effort to conserve precious battery backup for the system, after testing BPQ on Linux, I’ve now migrated MSTLCO & STLBBS over to a Raspberry Pi 2.

This also makes it incredibly portable and lightweight should the need to relocate the BBS in an emergency arise. Please let me know if you have any issues with the node or BBS after today.
