Created branch for Global Clock idea

This is an idea to use Several Timer interrupts to manage a global clock.
In this way any functions can be registered for either periodic or single
execution without needing to register a hardware interrupt.
Named Time functions with units

Added more time functions specific to seconds and microseconds. Any second functions simply call their us counterpars with the correct
conversion. Seconds is marked with an S and microseconds with US.
Fixed Tabs in time.c

Really, when would you ever need tabs TWO SPACES LONG
Merge branch 'master' into global_clock
