android: option to punt to sbt to build

[jimfulton]

Building android applications is complex. :)

I've gotten sbt to build my project, which involves multiple apklibs and various proguard settings. I'd rather not figure all of that out again for IDEA.

With the SBT plugin, IDEA will let sbt do the heavy lifting.

I can set this up myself when I create a run configuration.

It would be nice, IMO, if sbt-idea would generate run configurations for me and provide an option to let sbt to the work.
