make wifi interface a little more friendly

Browse Source 
For #5 make wifi interface a little more friendly.

* Add an index.html page to the SPIFFS tree
* Add a favicon because browsers spam the network for it if they can't find one, and the ~2KB of storage is a small price to pay.
* Add some more info to the info page which I have found useful.
