More grid changes, closer to final specs.

* Added isScalable, minCellWidth, minCellHeight, and borderSpacing attrs

When isScalable is true, we use set workspace cell values to
minCellWidth/minCellHeight and then scale the cell values to
fit the available space. This allows us to have consistent
aspect ratios when two devices match the display/grid options.

This is different from the dynamic grid, which calculates
cell values based on iconSize/textSize/etc and then allows
the cell width to be as wide as space allows.

I adjusted some variables so that they will auto adjust
based on another value, indepenent from whether the
grid isScalable or not. An example of this is the folder
label text, where it's always set to be 1.14x of whatever
the workspace icon text size is. This is so we don't need
to add a bunch of more variables to DisplayOption/GridOption.

Test: - switching between device profiles,
      - testing folder open/close
      - testing in multiwindow
      - testing in landscape
