Added correction for dataline, needs to have bit set to 0 at start up as
it sometimes comes up in a state that allows normal function after power
loss. increments for minutes and hours for switches set to functions to
be reusable for alarm setting.
Fixed am/pm in hour set, moved to inside if with increment. duplicate
code at this point, needs clean up. Alarm set is implimented but no
comparison is done yet (will display alarm).
Created #defines for code readablity
Update readme to reflect current state of project.
