* Replacing Net.HttpListener with HttpServer. 

* This is a HUGE update..  and should be considered fraut with peril.
* SSL Mode isn't available *yet* but I'll work on that next.
* DrScofld is still working on a radical new thread pump scheme for this which will be implemented soon.
* This could break the Build!  This could break your Grid!
