* migrate away from REST API for inter-dvmhost operations towards a custom UDP RPC framework;
* replace config parameters for REST API in some places with properly named RPC; swap peer Network, FNE DiagNetwork and FNENetwork over from if-else-if ladders to switch statements (switch statements perform logically better after compilation because the compiler tends to optimize these into jump-tables which execute faster);
* continued work on inter-dvmhost REST to RPC transition;
* update build bumper for R04G20 to R04G21;
* cleanup config file;
* clean up doc/commenting;
