Adds directory names to the files in working tree, when multiple files with the same name are opened there.
Changed font size of directory to 11px and using mdash as separator
Fix bug #4486 (JSLint icon has no tooltip in some states) - Don't use CSS
to filter clicks on icon depending on state, since killing all mouse events
also breaks tooltip. Use JS to filter instead.

Also clean up some comments, and remove confusing unused/unimplemented
argument in StatusBar APIs.
Make folder tree refresh menu item less ambiguous (could be interpreted as
refreshing the single file that was right-clicked).
Enhance status bar to show length of selection (cols if within a single
line, line(s) or partial lines if selection spans more than one).

Hoist out \t converion logic from EditorgetCursorPos(). Add unit tests for
it.
