Network base code and example app bundle with account/session support.

This is a 'tagged' version of the sim-eth-basic example that doesn't have any game-specific networking components added to it but does have some starter account session and game session support. This can be used as a pretty good cut-paste template for any JME networked game with a similar 'login' then run approach.

This this forum post for details and instructions:

I may split this off into its own separate example at some point but I didn't want to get bogged down with maintaining two different code bases when I have a longer term goal I'm working towards.

sim-eth-basic.zip contains a "ready to run" version of just the base example at the point of this release.
sim-eth-bacis-sources.zip contains the build files, assets, and source files necessary to cut-paste into your own base game.
