[cp-patches] FYI: JTable cell editing implemented and committed

[Anthony Balkissoon]

This patch implements DefaultCellEditor and some methods in JTable in
order to make editing JTable cells possible.

A demo will be added shortly, for now I am attaching a small test app
that you can use to test the editing functionality.  With a table cell
selected, pressing F2 starts editing and then pressing ENTER stops
editing.

2 notes:
- the test app appears to draw incorrectly at the top, this is due to
some trouble in BasicViewportUI
- if you edit more than one cell, you will notice that text from
previously edited cells appears in the cell you are currently editing,
this is due to bugs in JTextField/JTextComponent

Patch is attached.
