[DONE] Scroll-allocation in Research/Manufacture GUIs

[Meridian]

It is now possible to change allocated scientists and engineers on a project without opening extra GUIs, directly in base GUI using mouse scrollwheel.

Normal scroll +/- 10 scientists or engineers
CTRL + wheel +/- 1 scientist or engineer

The step is configurable via options.cfg, if you don't like the defaults.
