Before this commit, environments grouped together in a "folder" would
include the folder name in the UI.  This information was unnecessary

Adds CSS for child envrionments

 - Split layout from the styles of the row
 - Move command `.append-` `.prepend-` styles to bottom of source order

    - Also allows us to get rid of some styles that were trying to get
      around this fact
