Randomize advanced Envelope parameters

[mlazarev]

The library contains code for randomizing on/off buttons for Multi-Trig, Sync, Loop, and Latch settings of the envelope. However, turning these one creates a chaotic sound, often bleeding into the next patch (while switching) because the envelopes do not reset cleanly. I have disabled randomization of these but may come back later for a more advanced randomization preset.
