Tony and I implemented HOME and END actions for text components.
Unfortunately, we tried to implement a more efficient solution but
viewToModel was not returning the proper values. I added a TODO comment
in there, so it could get looked at later once we have viewToModel
fixed.

* javax/swing/text/DefaultEditorKit.java:
Added implementation for beginLineAction and
endLineAction.
* javax/swing/text/JTextComponent.java
(JTextComponent): Added key bindings for HOME and END.
