Moving to POST based on upstream status (Implemented).

I am working with multiple engines for a while on 5.0. Only paths not tested here were multiple engines on distributed machines and esoteric settings. Default settings and several engines on the same machine works rather well.
There is still some work to be done as to how its all being logged and monitored.
Setting this to modified as the original thought behind multiple engines is supported.
Next versions will need a 'child' RFE for things not yet done here.
