I have started to implement the details view for the MetalFileChooser.
It is not yet complete.
- It doesn't update when the different control buttons are pressed
(home, up.. etc)
- It does not render the icons yet
- It does not have a doubleClickListener attached
- It does not have a singleClickListener attached (for editing)
The table appears when the details view control button is pressed.
Also, I implemented the functions to get the preferred and minimum
sizes. Since the wrapping for lists is not yet complete, the size is
not right yet.

* javax/swing/plaf/metal/MetalFileChooserUI.java
(DetailTableModel): New Class implemented to override selected
methods in DefaultTableModel. More methods will be added later.
(ListViewActionListener): New class implemented.
(DetailViewActionListener): New class implemented.
(completeEditing): Set boolean to false.
(mouseClicked): Added check to make sure editing only starts
when left mouse button is clicked.
(editFile): Set boolean to true.
(actionPerformed): Set boolean to false.
(createList): Commented out wrap code until JList bug is fixed.
(createActionMap): Added action for cancelSelection.
(createDetailsView): Partially implemented to display details
view table.
(formatSize): Private function added to convert bytes to an
appropriate size String for the table.
(getPreferredSize): Implemented.
(getMinimumSize): Implemented.
(addControlButtons): Added action listeners for detailButton
and listButton.
(setDirectorySelected): Added API documentation.
(getDirectoryName): Likewise.
(setDirectoryName): Likewise.
(valueChanged): Likewise.
