Added intellij plugin to build.
Added support to build for publishing to Bintray (and then JCenter). Switched from maven plugin to maven-publish plugin to support bintray upload. This removes the install task, but jar can still e installed using publishToMavenLocal task of new plugin. Also added the release plugin to make releasing new versions a single command.
Merge pull request #3 from JayStGelais/master
