Package re-org in advance of 2.1 RC.

* Proxy specific places and activities are half baked, and have been
banished to the expenses sample (which will later be updated to use
them)

* com.google.gwt.app has been broken up into gwt.place and
gwt.activity

* ui classes that depend upon RequestFactory have been moved to
gwt.requestfactory.ui.client

* various new widgets have been moved user.client.ui

* Separation between ValueBoxBase and TextBoxBase is complete, with
introduction of ValueBoxBase#setAlignment(TextAlignment) and the
TextAlignment enum. TextBoxBase#setTextAlignment is deprecated

* parsers and renderers have been moved to gwt.text.client, have unit
tests, and are localized

* various stupid and / or unused classes have been deleted
