Added beat88 and beatsin88
Added CRGB::getParity, CRGB::setParity, and fairy light color apporximations: CRGB::FairyLight and CRGB::FairyLightNCC (for use with No Color Correction).
Added EVERY_N_SECONDS and several variations.  Some of it is preprocessor macros instead of templates because of C++03 template rules (which have subsequently been relaxed in C++11).
