Fix for bug 661
Introduce *DECIMAL-SEPARATOR* global for Nyquist. Improvements to numeric validation error messages. Fix *TRACK* START-TIME and END-TIME properties for tracks with different length channels. Update Adjustable Fade, Regular Interval Labels and Vocal Removal to use numeric text inputs. This does NOT fix bug 1020.
