todo
- make the filedialog windows like
  filename entry field shows only the filename not the whole directory
  the tree always starts in current directory
  the parent tree is shown in a combobox where the perents are selectable

- do not expand the ~ or relative pathnames to absolute pathnames

Class protocol:

accessing
o  additionalFolderItemsInMenu
any additional folders to be shown in the 'File' menu;
each element can be either a filename or a pair with filename and menu-item-label.

Usage example(s): 

FileDialog additionalFolderItemsInMenu:#('/Users/exept' ('/Users/exept/cg_work' 'WorkDir'))

o  additionalFolderItemsInMenu: aCollectionOfFoldernames
any additional folders to be shown in every 'File' menu;
each element can be either a filename or a pair with filename and menu-item-label,
or an assoc, with key=filename and value=label.

Usage example(s): 

FileDialog additionalFolderItemsInMenu:#('/Users/exept' ('/Users/exept/cg_work' 'WorkDir'))

o  additionalFoldersInDirectoryMenuQuery
can be answered with a list of addotional folders
(expecco does this to add eg/ the attach,emtsFolder(

Usage example(s): 

     FileDialog additionalFoldersInDirectoryMenuQuery 
        answer:#('/foo' '/bar')

Examples:


usually direct access to FileDialog is not recommended; please use the Dialog interface, which is able to dispatch to alternative file choosers if the settings say so (native dialogs, for example): 
  |fileOrNil|

  fileOrNil := Dialog requestFileName:'Choose a File'.
  Transcript showCR:fileOrNil
simple examples: 
  FileDialog 
      requestFileName:'enter a fileName:'
      default:''
      version:nil
      ifFail:['none']
      pattern:'*.conf'
      fromDirectory:'/etc'
