ofArduino macros

[colormotor]

I had some problems because of macro definitions in ofArduino.h overriding an enum in a a class of my codebase ( SHIFT )
It's not exactly a bug! but I would suggest using enums or const int instead of the macros to avoid any conflicts
I solved the problem by modifying

define SHIFT 0x05

into
const int SHIFT = 0x05;

another solution could be using enumerations as
enum
{
...
SHIFT = 0x05,
etc...
};

I believe this would not break any of the existing code

Yes, this has also just caused me problems when working with Qt. Qt defines SHIFT within a namespaced enum, but if OF is included first then this leads to a cryptic compile time error which compalins about Qt but makes no mention of ofArduino.

For compatability I would suggest changing to const int SHIFT rather than the enum as these are not always interchangeable with integers.
