Knob (#600)

Resolved issues with history due to merges, opened a new pull request.
A more visual widget that the usual number/slider. Differentiates itself
from the functionality of a slider by not setting the value on click,
only stepping, emulating an actual knob.

- Left/Right takes 1 step at a time
- Up/Down moves 1% or 1 step, whichever is larger
- Move + Shift moves by 10% or 1 step, whichever is larger

This also includes a fixes to some size logic.
- [x] ~~Still missing being able to drag the knob itself, as the
clicking of the widget is not recognized if it's outside of where a
normal height widget would be.~~
