Multiselect nodes, Move multiple nodes around at once (multi select, multi-select)

[DarkTrick]

Is your feature request related to a problem? Please describe.
Moving more than three nodes around becomes kind of a hassle, because only one node can be selected / moved at the time.

Describe the solution you'd like
I'd like to be able to select multiple nodes (with shift or ctrl) and then move them around at once.
Selection UI would be as in file browsers: ctrl is used for single file selection. shift is used to select from, to.
