HashTable.add

This is a convenience function for using a #GHashTable as a set. It is equivalent to calling g_hash_table_replace() with @key as both the key and the value.

When a hash table only ever contains keys that have themselves as the corresponding value it is able to be stored more efficiently. See the discussion in the section description.
