I added stringrep, which is a cpp replacement for some c string functions.

They're all really simple, and maybe could even be optimized.  I did this so
that you could use the old c functions when you wanted to, but with cpp memory
management.  Also, some of these don't exist on other platforms, so it makes
other programs more portable.

The new functions are just like the c ones, only named string* instead of str*,
for example stringdup instead of strdup.
