Oscillator Retrigger is not implemented for a number of oscillators

As it stands currently (before 1.8 release), oscillator retrigger parameter is only valid in Classic, Wavetable and S&H Noise oscillator types. All other oscillators are blissfully unaware of this parameter and will always retrigger from 0° on every new note played.

For 1.9, "the oscillator release", enable this parameter for all oscillator types, and handle streaming so that old patches using the affected oscillator types are loaded with Retrigger button enabled, if it wasn't.

Actually, retrigger is implemented for Window, but curiously only if there's more than 1 unison voice selected. This is unexpected behavior in my book. Sine, FM2 and FM3 literally don't have it implemented. It's actually commented out in FM2/FM3, heh!
