Crash on 'toLowerCase' in handleConfigMessage

[robotconscience]

Not sure if it's: https://github.com/Spacebrew/spacebrew/blob/1b56f168dfcb5f1588cf76efc575124bd8d6e2f3/spacebrew.js#L718

or

https://github.com/Spacebrew/spacebrew/blob/1b56f168dfcb5f1588cf76efc575124bd8d6e2f3/spacebrew.js#L732

or both? But seems like this is one of the places the current server is crashing:

(log below from Amazon):
