Transform/UI: individualize the option to use snap per editor type

`3DView`'s `use_snap` option has little or nothing to do with using
snapping in `UV`, `Nodes` or `Sequencer`.
So there are no real advantages to keeping these options in sync.

Therefore, individualize the option to use snap for each "spacetype".
