Closes #1795

I have created this simple css autocomplete/hint that uses data from
the css mode. Autocomplete works for both properties and values - but
it does not filter the values by property. Better than nothing for
now.

Use 0 instead of 0px, clean-up two line breaks, to fix lint warning;
Three empty CSS blocks could also be removed.

Node provides some cross-platform utility methods to enable safe
path traversal.

This change merely swaps out a hardcoded '/' (unix path separator)
to use one of these methods.

An alternative strategy would be to use the constant 'path.sep' but
this felt 'cleaner'.

Previous behaviour was to only update the displayed differences if
the edit pane was modified.  There exists use-cases such that the
differences should be updated when any of the panes change.

I don't expect this to introduce any performance regressions due
to the existing debounce code within the update function.

Removed the redundant "List of contributors..." line

Subdirectories no longer contain separate LICENSE files. Delete
the note to them from the top level LICENSE.
