Fix WiFi setup

Browse source 
* Increased the number of APs that can be queried and filtered out those that have an RSSI -95.  Previously, the number of returned SSIDs could blow the output buffer.
* Do not disable the Save button during scan of potential APs.  If the scan is taking a long time you should just be able to type it in.
* If a connection is lost and cannot be recovered fall back to AP mode to allow resetting the creds without power off.
