Default font looks better with no serifs on 'T'

[bperrybap]

The default font in glcdfont.c is using serifs on the capital T
it is single pixel hanging one pixel down on each end of the horizontal line.

When animated (moving horizontally) on led panels, it looks like the top line is two pixels wide rather than a single like with serifs because the font is so narrow and a bit of persistence of vision.
It looks much better when the serifs are removed.
No other character is using serifs.
Here are the codes for 'T"

//	0x03, 0x01, 0x7F, 0x01, 0x03, // 0x54 T (with serif)
	0x01, 0x01, 0x7F, 0x01, 0x01, // 0x54 T (without serif)
