Twili 1.4.0 (preview 1)

It's been a while since I did a release, and 10.0.0 support has been waiting for a long time. This is a version that I can finally feel comfortable claiming that it at least mostly works on firmware version 10.0.2. There are still a few rough edges and things to make sure I didn't break (namely, support for firmware versions below 10.0.0) before I do an actual release, but I wanted to get this out there since it's been waiting for so long. Have fun, and ping me with any problems!

(also, sorry for no osx twib binaries, there's some travis issue that I have yet to work out and that I didn't want to let block this release)
