0.2.2

• Fix ArrayIndexOutOfBoundsException in mutable.BitSet#<<= (#86), thanks @linasm
• support Scala.js 1.3.0 and drop support for Scala.js 0.6 (#109, #96)

This release was brought to you by 5 contributors, according to git shortlog -sn --no-merges v0.2.2 ^v0.2.1. Thank you Scala Steward, Seth Tisue, Linas Medžiūnas, Philippus, Lukas Rytz.

A note on semantic versioning: 0.2.1 should have been 0.3.0, since it had real additions and not just bug fixes. This time, we only have a single bugfix (#86) and no other user-visible changes. So this is 0.2.2, but we'll go to 0.3.0 the next time there are actual additions.
