Support for UNC paths in local tree pane

[Daniel Beardsmore]

When using a UNC path for local files, the “Local site:” box will accept and show the current path, but the server node and directory tree does not appear within the local tree pane. This means that you cannot explore the local directory structure or move files between local directories.

I would expect the server to appear as another node in the tree, either at the same level as local drives, or at the same level as Desktop, and a chain of directory nodes up to the working directory.
