Wifi reliability (#45)
* First pass at wifi inbound FSA
* Fixup detector loop
* Remove asyncBanned
Unused, uninitialized
* Move wifi setup loop out of .ino
Wifi auto detect Serial 1,2,3
* Correct capitalization
* Uno compiles clean
* Command distributor
Moved command execution routing out of Wifi code for future use by Ethernet interface.
