[DelphiAsioVst-SynthEdit] Transistor based analog ringmodulator added

[Christian B. <Chr...@ai...>]

Hi there,

based on this 
(http://dafx09.como.polimi.it/proceedings/papers/paper_24.pdf) 
interesting paper from this years DAFX conference, I just implemented 
the proposed transistor based ring modulators and compiled them as SE 
module.

They are located in the existing ring modulator module.

Enjoy,

    Christian
