Add recursion to the mixers

[GoogleCodeExporter]

To the mixer lines screen, add possibility to select CH1-CH8 as input signal 
for the mixer. You can say for the most of the cases we can use virtual 
channels ( X1-X4 ) for this purpose, but sometimes would be very convenient to 
have this function. I see only one dangerous place, to exclude situation with 
endless loop, when in simple case CH1 is input for CH1.

Do you have examples where you need this.

The current Implementation would need, that you can only use output channels 
which are already calculated. e.g. CH5 = 50% of CH3, but NOT  CH3 = 50% of CH5.
This feature would need a changed model memory layout.

If we need a more flexible usage (CH3 = 50% of CH5) then a more complex change 
in sw is needed. (which leads to more bugs)

Is this really necessary?

PLC's work that way, all the processing is done in a linear way, and the IO is 
updated synchronous. The coder (software programmer) decides by the sequence if 
a change is processed this slice, or the next slice, by the sequence.

So CH3 changing as result of CH5 can be done, but will see the output 1 slice 
(22.5 mSec) later.

Seems you can close it, because you implement it in release 199. Am I right ?
