Richchanges

These changes are basically in support of running the app from the command line. I tweaked the existing start_in_shell.sh to explicitly start all the prereq apps because, for some reason, they weren't getting started by the app itself. I spent a lot of time trying to debug this to no avail so I gave up and did this.

The biggest change was adding a rebar generated release that contains everything in one package (the "rel" directory) and it can also start the app from the command line.

Finally, I cleaned up the lager stuff and added some lager configuration info to make the logged messages easier (for me) to read.
