Christopher Snowhill 9c6915ecb2 Implemented real pitch and time shifting using Rubber Band
I will implement the more complex setup of providing options for
most of the configuration that Rubber Band provides, at a later
date, when I feel like creating a complex configuration dialog
for it, and asking for help translating every option and setting.
