SimEtheral 1.1.1 - Bug fixes and small improvements

This is a small patch release over 1.0.1 that includes a fix for the message splitting bug along with more control over when messages split. There were also several improvements to exception messages.

Release includes:

• Added an EtherealHost.setConnectionObject() to make it easier
  to set the connections object ID and initial position. The older
  way required some tighter coupling to Ethereal internals.
  Old way to start hosting on a connection:
  getService(EtherealHost.class).startHostingOnConnection(conn);
  getService(EtherealHost.class).getStateListener(conn).setSelf(ship.getId(), new Vec3d());
  New way:
  getService(EtherealHost.class).startHostingOnConnection(conn);
  getService(EtherealHost.class).setConnectionObject(conn, ship.getId(), new Vec3d())
• Improved an exception message on LocalZoneIndex's out of bounds checking.
• Improved an exception message in FrameStat's split() regarding a failure to split. The message
  now includes the caller specified limit so we can see if it's even a sane value in these
  error cases.
• Attempted fix for a message split bug (untested). Based on the logic, there were some
  book-keeping items not properly updated which could lead to exactly the error cases
  reported. Hopefully fixing those calculations fixes the problem but I've also left
  a ton of comments in place.
• Added a StateWriter.get/setMaxMessageSize() method(s) for controlling the MTU size used
  to calculate when messages are split. So even if the above fix doesn't work then callers
  can effectively turn off the split behavior by setting a huge max message size.
• Exposed get/setMaxMessageSize() at the NetworkStateListener level so that application code
  might set this value on its own, or even dynamically, based on application-specific
  requirements.
