Needs implement set clock

[AlmuHS]

At moment, the clock runs as a counter, adding seconds, minutes and hours, but isn't possible set the hour (with hours, minutes and seconds) in the clock.

There is a simple try to implement, but it cause problems with ports (VHDL don't allows to assign the same port to two inputs)

To get the binary clock runs as a real clock, It's necessary to implement this functionality.
