#2 Revert action

[Zbigniew Ogledzki]

That would be nice to have an "revert" action (button
for example) on the property sheet (bellow the list).
The action should then revert to last saved version
(in the simplest form), or (in the more advanced one)
have two possibles:
1. to the last saved version
2. to original (got when opened).

Feature not important, but nice.

There is a simple undo at the right click menu, but it isn't
very stable. We could implement a visible list for choosing
some older content, also!

Well I think we should use the
javax.swing.undo.UndoManager used for every entry, or -
simpler a little - a Collection for every entry to
undo/redo actions.
