Unit Rulers

We have added a new ruler-system for units, that draws distance lines from the selected unit's front, back and sides to other units or obstacles. The ruler can be toggled on and off with the "R" shortcut or you can use the icon in the top-bar.

Bugs and Fixes

• The code for creating an outline on unit-selection caused some heavy loading times. We have reduced loading time by disabling this for when the mesh is too complex
• The input for zero-line position on vessels now updates correctly in the 3D view
• Changing the names of cranes and mezzanine-decks now properly updates in the Ui
• Removed the Drawing Position inputfield on grillages
