    FileBrowserV2 is based on Filebrowser

    WARNING: files edited with FileBrowser will have leading spaces (multiple-8)

             being replaced by tabs. If tabs are to be preserved at other

             positions (for example, sendmail-config files) they will be

             corrupt after being written.

    [instance variables]:

        checkDelta      <Integer>       number of seconds of check interval

                                        (looks ever so often if shown directory

                                         has changed). You may make this number

                                        higher, if your network-times are

                                        incorrect and thus, the filebrowser

                                        checks too often.

        compressTabs    <Boolean>       if true, leading spaces will be

                                        replaced by tabs when saving text

    some of the defaults (long/short list etc.) can be set by the resource file;

    see FileBrowser>>initialize for more details..

toDo

"

    - the tab for the directory description text editor is not changed if the 

      directory description changes to a normal text editor

    - FileDialog should get a file history

    - directorycontentsItem isDirectory fails if it is a symbolic link

    - on sort order change in directory contents browser the columnspec shouldnt not reloaded

    - check all windowspecs with different font types

    - multiple select with mouse moving is flickering (see bestFilename in FilenameEditField)

    - too many system calls on update cycle

    - stop monitoring task for DirectoryTreebrowser and DirectoryContentsBrowser
