Issue:
Improve grid line labels in farm designer
# Expected Behavior
The grid line labels (`100`, `200`, etc) should be legible at all zoom levels

# Actual Behavior
At 0.75 zoom and farther out the labels are too small to easily read.

# Suggested Solution
- [ ] Scale the labels inversely to zoom level so they always stay the same size to the user, despite zoom level
- [x] At zoom level 0.5 and farther out switch from labels every 100mm to every 200mm
- [x] At zoom level 0.2 and farther out only show labels every 500mm
- I think a good size for the text might be where the bounding box rendered on screen is 16 to 18px tall. This might take some tweaking to look good.
- There may be some legibility issues with the labels on the left if when they stretch into the darker brown or even gray areas, which may require tweaking. Ideas: adding a text-shadow, making the font bolder or darker in color.

Table-ize Settings
Restructure settings that have X/Y/Z options into easier to read and more compact tables. Applies to Axes, Motors, Stall Detection, and Error Handling sections.
