fixes for java.util.Vector

[Patrick Tullmann]

Here are some fixes for java.util.Vector so that a Vector can be used
through the AbstractList interface.  I just added add() and set(),
which was enough to get an app I'm using to work on Kaffe.  

(I didn't realize how gross Vector had become when they retrofitted
java.util.AbstractList onto it... most methods are duplicated in the
new Vector.)
