Added the use of sample exact controls to the Delay plugin

Browse Source 
Added Sample exactness to the following parameters

Delay time
Regen
Lfo time
Lfo amount

Did not add this to the output gain contol, This model is used in
a dbScale, and a much more pleaseing result was gained by using an
amplifier plugin.
