Hardcode pitch-shift algorithm (for now)

Browse source 
This fixes an issue with pitch-shift using the most recently used
time-stretch algorithm, which may be "resample.." (effective NO-OP).

Also leave a ToDo note regarding rubberband crispness levels for later.

* TODO: also show stretch_opts_selector when pitching (except the option
* to not preserve pitch) and use separate rb_current_opt when pitching.
*
* Actually overhaul this the dialog and processing opts below and use rubberband's
* "Crispness" levels:
* -c 0 equivalent to --no-transients --no-lamination --window-long
* -c 1 equivalent to --detector-soft --no-lamination --window-long (for piano)
* -c 2 equivalent to --no-transients --no-lamination
* -c 3 equivalent to --no-transients
* -c 4 equivalent to --bl-transients
* -c 5 default processing options
* -c 6 equivalent to --no-lamination --window-short (may be good for drums)
