Improving docs

[markxr]

Hi,

Is there some way we could improve the docs? Can I clone the git repo and just send pull requests?

There seem to be some features which aren't documented at all (RTC memory, I found a bug in it, but the rtc ram wasn't documented in the esp8266 micropython, although it is documented on other esp8266 environments and quite useful).

Also I just found this setsockopt(socket.SOL_SOCKET, 20, callback_func) which sets a callback for a socket - which is potentially useful but totally undocumented.

Docs are managed in the repo, generated using sphinx, in the reStructuredText format and using Read The Docs styling.
