And a bunch of general housekeeping as I was in the area.

To address #18 and thus fix https://github.com/ensime/ensime-server/issues/473

Somebody who knows sbt plugins better (@fommil??) should review the spec config side, there are some depreciations but I have no idea how to address them.

[rorygraves]

Cool!, can you publish a new version?

😀 and the whole scala world gets one extra badge (then quickly turns it off again when they remember how bad their coverage is)

[rorygraves]

lol, that thought had crossed my mind :)
Ensime's coverage definitely counts as red - even after all the work done so far (although I accept 50% is better than the not measured.

0.99.0 is now released.

Thanks for the work on this.
