Changed address format and storage
 - Changed address to an array of bytes instead of oversized int
 - Added a reverse function to convert address from IP like (big-endian) address to little endian address which the radio wants
 - Tweaked some function names
 - Added pipe0 status to detect when it has been set and changed by an autoack so it reset when listening begins again
 - Fixed a few more defines, the last I swear
 - made everything prettier
