Adding pango patch (ref. #10)

Text from original patch:

Using pango markup for status text

Use a single font. Removed some code utf8 code from drw.
Created for pango 1.44. Older versions might not have getter
for font height, ascent + descent can be used instead.
All texts are rendered with pango but only status is with
markup. Increased stext size (in case a lot of markup is used).
MIN/MAX is already defined (didn't redefine them).
