Fix #195. AbstractButton no longer implements HasHref and HasTargetHistoryToken. AnchorButton now implements HasHref and HasTargetHistoryToken. AnchorButton's target history token handling is improved based on Hyperlink's implementation.
Revert Text to 0.7-version (Fixes #137)

If onAttach/onDetach are not overridden then those are called from widget where
DOM.setEventListener(getElement(), this);
is called.
This method is apparently not available for text nodes in IE8.
