convert a string expressing a pitch in Scientific pitch notation into its equivalent midicent encoding. The scientific pitch notation is the notation used in the specification of pitch in events. For example, "A4" is converted into '6900'. The function also accept pitch specifications starting with a minus sign '-', like those used in Antescofo musical event specification to denote the continuation of a previous note. The minus sign is simply ignored in the translation.

NOTE: the microtonal alteration, as in A#4+50, are supported.
