Release Notes:

Details: Implemented a contributor fix, adding method
    "removeAllItems" to component baselist.  I sent
    this out for review last fall, but it never got
    checked in.

Tests: Run the following:

<canvas width="500" height="300">
    <list name="list1">
        <textlistitem text="soln1" selected="false"/>
        <textlistitem text="soln2" selected="true"/>
        <textlistitem text="soln3" selected="false"/>
    </list>
    <button y="80" onclick="list1.removeAllItems()"/>
</canvas>

Click the button.
