Remove measurement tool units from preferences (UX)
Current Behaviour
The measurement tool units are what was last used (as set in preferences), mm by default
Proposed Behaviour
The measurement tool units are whatever the display units are (as set in Document Properties).
- Provides consistency with other tools (select, rectangle, ellipse, node)
- Changes when display units are changed (but can be changed manually)
- Changes with new documents
