The point of this change is to be able to do
g_hash_table_insert(table, g_strdup(blah), baz);
and then when you remove that entry later, the key will be freed.
This is useful for tables where all the data is dynamically generated,
not kept in static tables of strings.  It's important to have because
there is no other intrinsic way to free the key.

I did it because I thought I needed it in gnome-linuxconf, but then
realized that because of hysteresis inherent in the design of gnome
frontends, I needed to have the string around separately and might
as well free it myself anyway.  :-)
