WiFi on ZX-Uno is supported by default now

Hello, guys!

Great news! Now you doesn't need custom core, but only
EXP27 core and you can use any WiFi utils(if you have WiFi
addon of couse).

BTW, WiFi addons for ZX-Unos now available from Antonio 
Villena! Go to https://antoniovillena.es/ and buy one!

I think there some result of my work too :-)

I'll try to find time and begin network manager for
ZX-Uno.

Also there some ideas about porting gopher browser
even for Vanilla Speccy 128+ with UART WiFi modem.

It will require some custom work, but I think this
is possible.
