There are some accessibility issues in the dialog
"Contents"

   To reproduce the bug:

   1. Create JarRecipe, select it in the Explorer,
call Properties window
   2. Push "Contents" sheet button
   3. Push "..." button, dialog "Contents" appears
   
#1:  There are no mnemonics for <Source> and
<Chosen Content>.
     It is impossible to jump in the tree or in
the table with shortcuts.
     
#2:  Buttons ">", "<" and "<<" should have ascii
names and mnemonics. 
     Otherwise user is not able to know, what keys
to press for adding or removing items.  

#3:  If we tab in the non-empty tree, first
element in the tree should be highlighted.
     If we tab in the non-empty table, first
element in the table should be highlighted. 

#4.  Initial focus is on the tree, it is correct.
     If we push "Tab", focus is on the horisontal
scroll bar, it is wrong.
     When focus is in the tree, user can move the
scrollbar with Ctrl-right or Ctrl-left arrows. 

#5:  Select one element in the tree. Button ">" is
enable. It is correct.
     Push tab 4 times and see that button "<" is
enable too. 
     It is wrong, no elements are selected in
table <Chosen Content>. 
        
#6.  If to select <Directory Prefix> via "Tab",
blinking bar is in the combobox.
     If to select <Directory Prefix> via Alt-D,
there is no blinking bar.
     It is impossible to enter the text.
BTW, could you explain, why there is no <Directory
Prefix> in "New Wizard-Jar Recipe" window, when we
are creating jar?

Note, that items #1-5  are the same for panel
"Specify Jar Recipe Contents" in Wizard window.
