The value field is currently a staticly defined array of characters
with a set limit of 128 characters. It is defined that way due to
the fact that characters are added one at a time to the value field.
A real fix will require going to a chunck based structure or
doing multiple StrAllocCats which would seem horribly inefficient.

Since I'm lazy I just increased the VALUE_SIZE to 1024. That should
handle most of them until we can get a real solution.
