Can no longer set background color using picker tool

You used to be able to set the BG values by right clicking on an image with the picker tool active. Now the context menu comes up instead. Though one can set FG values just fine it is now impossible to set BG values using the picker tool.

(Curtis, if this is a result of recent work that you can fix quickly please take. Otherwise assign back to me.)

You can avoid the ContextMenuHandler picking up the right clicks by adding the following code to PickerTool:

	public void onMouseDown(final MsPressedEvent evt) {
		// do not let anything else handle mouse presses

	public void onMouseUp(final MsReleasedEvent evt) {
		// do not let anything else handle mouse releases

However, there is another problem in that PickerTool.onMouseClick currently does not do anything in response to right clicks. Rather, it sets the BG value when the Alt key is held.

Lastly, I noticed that PickerTool detects the Alt key by overriding onKeyDown and onKeyUp. You shouldn't need to do this; you should be able to call evt.getModifiers().isAltDown() on the MsEvent directly. Please let me know if this does not work.

In commit c1cf7fb63d05bdfbe11e3fbfd2b7b4ef8c47a11b used standard methods for tracking ALT key status.

There really is nothing else left of this ticket.
