Serious crashing bug in STRHTMLCLEAN with multiple duplicate FONT
tags, fixed.

STRHTMLCLEAN was not correctly cleaning strings with overlapping
font tags, fixed.

Test example:

drawclear white
a = "G<font size=\"3\"><font face=\"times\">o<font
face=\"arial\"></font>o<font size=\"3\"></font>d</font>b</font>ye"
messagebox @a strhtmlclean(@a)
exitnow


Added error checking to key ItemAdd and ItemAddUnique low level
functions. They would crash if given a negative byte count.
