FLUME-281: Allow System property-based specification of FLUME_HOME/FLUME_CONF_DIR
Review Request #1048 - Created Oct. 19, 2010 and submitted
Allows users to specify -Dflume.home and -Dflume.conf.dir instead of $FLUME_HOME/$FLUME_CONF_DIR.
Adds new unit test. All existing unit tests pass. Also embedded Flume in my application in an application server without $FLUME_HOME set in the environment. Flume works with this patch + system-property setting, and doesn't work without it.
Sorry - I reviewed this but never gave it a ship it. It's already in master.
