Added the sbt-idea plugin.
Two fixes:
- The default HDFS input path now expands to the deepest level of the standard Camus partitioning schemes. You can override c2k.hdfs.input.dir if your partitioning scheme is non-standard.
- Added JVM reuse (set to 100) by default, since Camus data is not rolled up by default and can result in a lot of small files under some circumstances.
