Use most efficient node available

[mischakolbe]

Add a resolution setup that picks the most efficient node available to do the job.

Right now a simple 1D-multiplication uses the overloaded multiplyDivide node. That could be done in a more efficient multDoubleLinear. Same goes for plusMinusAverage & addDoubleLinear.

Also could check which node type would need the least amount of unitConversion nodes to get the job done.
E. g. multiplyDivide vs. animBlendNodeAdditiveRotation.

Good point, @kleinheinz . This entire issue might be something for NoCa v3, but it's definitely an interesting and promising one in terms of performance.
