#1 Larger display with no seconds

[Kithera]

from an email from Mr. Krebs:

"I would also recommend adding the option of displaying the time in a larger font, without the seconds. Perhaps a "-L" option or something like that. Temperature.app displays the actual temp in a font that appears double the size of the smaller font. I think that would be grand."

Add a new options which will display the time with no seconds, enlarge font to maximize space for this new drawing mode.
