* Returns a valid initial abstract path for the specified frame.

* - we first try to see whether <code>path</code> is a legal, existing URI.<br/>
* - if it's not, we check whether it might be a legal local, existing file path.<br/>
* - if it's not, we'll just use the default initial path for the frame.<br/>
* - if <code>path</code> is browsable (eg directory, archive, ...), use it as is.<br/>
* - if it's not, use its parent.<br/>
* - if it does not have a parent, use the default initial path for the frame.<br/>
* </p>
* @param path path to the folder we want to open in <code>frame</code>.
* @param folderPanelType identifier of the panel we want to compute the path for (either {@link com.mucommander.ui.main.FolderPanel.FolderPanelType.LEFT} or
* {@link #@link com.mucommander.ui.main.FolderPanel.FolderPanelType.RIGHT}).
* @return our best shot at what was actually requested.
