Speed increase.  Added the "sonic" routines by Bill Cox to reduce the length of eSpeak's sound output data, so as to make the speaking speed faster.

Ordinal numbers: Some languages (el,es) use the ordinal form of hundreds and tens part of a number, as well as the units part.  Added language option NUM2_MULTIPLE_ORDINAL.
