UI/UX enhancement: Change the snapping factor via keybinds and visualise result

[toebeann]

Summary

the ability to change the snapping factor without opening the settings menu, and visualising it so you can see the distribution of snapping points around you. This would make it easier and far more intuitive to tweak SnapBuilder for your preferences.

Hold a key + scrollwheel for scaling the factor? Hold the key and press middle-mouse to undo? Hold both key and middle mouse for a second to reset to default?

Or instead of always holding a key, perhaps toggle in and out of the mode with a key. Allow for both?

Controller keybinds will need some thought.

Visualisation should be simple, with three modes:

1. on whenever pointing at a surface with the build tool (Always),
2. on only when changing the snapping factor (Contextual?), and
3. off (Never)

Also consider: per-room type snapping factors which are stored in preferences, and perhaps set up defaults for each room type, with the ability to toggle between room-specific and global factors. (#50)
