Doesn't seem to support multi-folder workspaces

[cameronblandford]

Expected behavior:

1. Add two folders to workspace
2. Add a LESS file to each one, with variables
3. Import both into a third LESS file
4. When using the variables from the two LESS files, they should autocomplete in the prompt.

Actual behavior: 4. When using the variables from the two LESS files, only variables from the first folder show up in the prompt.
