Added color #defines for the colors in the time zone configuration menu, also updated some comments in the #defines for the timezone EEPROM storage addresses to not say the variable sare stored as two bytes.
Added timezone selector function to set which time zone should be used as the "current" timezone and created two dummy functions to wrap the time zone offset minutes from 0-59 and hours from 0-23 to avoid wierd values from the offset such as -1 or 24/-1 or 60 for the hour or minute after adding the GMT offset to the time.
