Add clusters config
	TODO: Validate deeper than one level

Add array support (discreet valid values) to besi.isValid()

Process besi.clusters [besi.cluster()]
	NOTE: We verify that each source is requesting a supported and available database, that each query has a valid source, and that each cluster has at least one source and query. We DO NOT validate the configurations here; this should be done in besi.doConfig() [and will be, soon]; until this is done, this code should not be used in any environment.

Switched to a different native mySQL library

Started adding mySQL functionality; need to rethink how to do this because what I'm doing now staight-up ain't workin'
