Update database and tables to InnoDB, utf8, auto_inc 1 and unsigned on some ints

[graphiclunarkid]

From the IRC meeting in #orgtechvols this evening:

(19:33:48) graphiclunarkid: One thing I wanted to ask, actually, is how we get more eyes on the middleware code. I see there's an outstanding pull request from someone from a couple of weeks ago.
(19:34:06) graphiclunarkid: I would just accept it - but I don't want to do so without someone reviewing the code first.
(19:34:15) graphiclunarkid: It looks pretty non-controversial though.
(19:34:40) dantheta1: Yep - that's the utf and innodb changes in the MySQL table structure. I'd say they're good to go.
(19:34:57) graphiclunarkid: #2
(19:35:11) graphiclunarkid: Oh cool, OK then. I'll merge them.
