Clocks

[SpaghettiBorgar]

This adds two ways to display the time:

• A nice big clock with 5x5 character digits right above the box
• Small formattable text in the top right corner

(screenshot below)

The small clock can be configured by a format string with the clock option and the big clock can be either turned on or off with the bigclock option.

If animations are disabled it will precisely repaint every full minute (for the big clock) or every second if the formattable clock is enabled.

I felt like this was missing in ly so I added these but still kept them disabled per default.
