Finally had the chance to rewrite "highcal" in C.

It's a little program that prints calendars, much like cal(1), but uses
more colors and can highlight dates fed to it via stdin.
highcal used to be part of gitodo:

gitodo and highcal were Ruby scripts. Ruby was an experiment at the end
of 2012. The language looked nice, but I have not gotten used to it.
gitodo itself has already been replaced by the much simpler "be":

So, no more Ruby for me. Phew.
