Fixes#1164 and thus also #1150, #1149, #1147 and #898.
* Move to latest version of SPIFFS
* Add SPIFFS porting layer for NodeMCU
* Add option to delete output if it doesn't fit
* Change FLASHSIZE to be in bits by default: default 4mb 32mb
* Add SPIFFS_MAX_FILESYSTEM_SIZE override
* Add notes on SPIFFS_FIXED_LOCATION
* Add 1M boundary
* Include the current version of the LICENSE
AFAIK no one uses the wifi.startsmart() and wifi.stopsmart(). Removing
them frees up an extra 20-25K of Flash to use as filesystem. So I have
added a new config define WIFI_SMART_ENABLE which is enabled by default
so the default functionality is the same, but if this is commented out
then this code is omitted.
I have also removed wofs and upgrade from this build as we no longer
support these.
