Fix getfontname().

getfontname() would incorrectly return strings of the form
"FONTNAME:SIZE", when it should be returning strings of the form
"FONTNAME:hSIZE"--notice the "h" in the last form.  However, the
internal font string needs to maintain the first form.  So, instead we
cut it up and insert the "h" in the proper location giving it the proper
form.
