Request: Update EspClass with Reset, Restart, getChipId

[EricLauber]

The esp8266/Arduino project includes implementations for several functions in Esp.h and Esp.cpp such as:

-reset
-restart
-getChipId

Code calling these functions will fail to build with EpoxyDuino with the message:

error: ‘class EspClass’ has no member named ‘restart’; did you mean ‘timeval EspClass::start’? (not accessible from this context)

The same functions build fine and work as intended within the Arduino IDE. Reset and Restart are similar, although Reset may not properly clear out registers. getChipId returns a uint32_t that includes the latter half of the ESP MAC address in decimal (such as ESP5435756).

My request is to add functions with these names to EpoxyDuino to support building source that calls them. I think it would initially be acceptable to have calls to Reset and Restart basically do nothing - that would still allow projects that use them to build properly. Maybe a step further would be to print to the console that a restart was happening and to end the program/sketch. For getChipId this could return a default value or number like ESP0000000 in all cases.

Please send me a PR.
There's a long tail of rarely used Arduino functions, macros, and vendor-specific extensions which are not yet implemented in EpoxyDuino. I'm counting on the community to add them as they come across them.
