Feature/seqware 1939 settings enum

* Control all .seqware/settings keys with an enum
* remove a few redundant or unused keys (OOZIE_APP_PATH, FS.DEFAULTFS, HBASE.MASTER, HBASE.ZOOKEEPER.QUORUM, MAPRED.JOB.TRACKER)
* Create a new utility that auto-generates a listing of possible keys for documentation
* Added ability to turn off formatting via the Eclipse formatting file (enums format weirdly and cannot be controlled in Eclipse)
