SBT, 2.11, and quasiquotes (WIP)

Hi @julienledem,

I just took a quick stab at this during a couple of back-to-back meetings. I've added the SBT build config, made a few changes to get the project to compile on 2.11, fixed all the deprecation warnings I could while still keeping 2.10 support, and changed a couple of the macros to use quasiquotes (mostly as a demonstration—I ran out of time, but the rest would be pretty easy to finish up, and I'm happy to try to make some time for it if you're interested).

Haha that's a nice one!
