Replaced dependencyReport with dependencyGraph.
Bumped SBT to 0.12.2.
Added a slew of additional JVM & scalac options.
IORC will not compile on Scala 2.10.0 due to toIndexedSeq signature change;
limiting compilation of IORC to < 2.10.0 - the rest will compile in a branch.

TIL: Be specific in your return types.
Published for all Scala versions (2.9.0 -> 2.10.0)
