class sOAuthSignatureMethod_HMAC_SHA1 in jQuery social stream 7

The HMAC-SHA1 signature method uses the HMAC-SHA1 signature algorithm as defined in [RFC2104] where the Signature Base String is the text and the key is the concatenated values (each first encoded per Parameter Encoding) of the Consumer Secret and Token Secret, separated by an '&' character (ASCII code 38) even if empty.
