Update to the wifi module (#1497) 

* Removed inline documentation for several functions and update comments
Since documentation is now part of the repository, the inline
documentation just adds to the already huge wifi.c

* Wifi module: add new functionality, update documentation

Functions Added:
wifi.getdefaultmode(): returns default wifi opmode
wifi.sta.apchange(): select alternate cached AP
wifi.sta.apinfo(): get cached AP list 
wifi.sta.aplimit(): set cached AP limit
wifi.sta.getapindex(): get index of currently configured AP
wifi.sta.getdefaultconfig(): get default station configuration
wifi.ap.getdefaultconfig(): get default AP configuration

functions modified:
wifi.setmode: saving mode to flash is now optional
wifi.sta.config: now accepts table as an argument and save config to
flash is now optional
wifi.sta.getconfig: added option to return table
wifi.ap.config: save config to flash is now optional
wifi.ap.getconfig: added option to return table

Documentation changes:
- Modified documentation to reflect above changes
- Removed unnecessary inline documentation from `wifi.c` 
- Updated documentation for `wifi.sta.disconnect`to address issue #1480 
- Fixed inaccurate documentation for function `wifi.sleeptype`
- Added more details to `wifi.nullmodesleep()`

* Move function `wifi.sleeptype()` to `wifi.sta.sleeptype()`

* Fixed problem where wifi.x.getconfig() returned invalid strings when
ssid or password were set to maximum length.

* fix error in documentation for `wifi.sta.getapindex`

* Renamed some wifi functions
wifi.sta.apinfo -> getapinfo
wifi.sta.aplimit -> setaplimit 
wifi.sta.apchange -> changeap

also organized the wifi_station_map array
