SODAQ in capitals in boards.txt
Add a copy of pins_arduino.h from 1.0.5 (variants/standard)

The reason is that we can now add certain SODAQ board specifics such as
"Grove Switched" pin. It's not yet added in this version.

Alas, we then also need a complete copy of cores/standard from Arduino IDE
installation. This is inconvenient, but that's how Arduino IDE was
programmed to do. Now we must be aware of potential incompatibilities
with Arduino IDE versions.
Add pin defs for Grove (Switched) Power, BEEDTR and BEECTS
