Declare pin handler struct as Global variable

In .ino file, global variables are assigned values before the structure symbols can be loaded into memory. This causes problems when global variables are used in Arduino sketch. Assigning value to pin handler structure in global scope removes this error.
Remove extra comma (,) in structures

Oops! by mistake.
Remove init() from wire.h

init() function in wire.h is wrong reference to the init() function in variant.cpp file. Compiler was confused by this declaration.
Serial port of CFA10036 is '/dev/ttyAPP3' now
Define F() function in WString.h

This function writes data(for arduino only) to Flash Memory. We do not need separate flash memory for CFA10036. So F() is a dummy function and returns the same argument.
Cleaning of code!

Organize code, Write/Rewrite debug message, Remove unnecessary white space.
Remove Capsense library from Makefile
