Added four new functions as shortcuts to creating GHashes that use the standard ptr/str/int/pair hash and compare functions. GHash *BLI_ghash_ptr_new(const char *info); GHash *BLI_ghash_str_new(const char *info); GHash *BLI_ghash_int_new(const char *info); GHash *BLI_ghash_pair_new(const char *info); Replaced almost all occurrences of BLI_ghash_new() with one of the above functions.
