Smarter module insertion

[Silt]

Currently, when you crtl-right-click with modules on a machine the affect is the same as crtl-left-clicking (except when the stack size is < 8).

It would be much better if it just puts one module in the machine, so you can fine-tune modules much faster.

You could also add another shortcut (like shift-crtl-click) that puts modules in the module slot, even if that machine has that module as input (e.g. speed module for rocket control unit)
