1. FastView completed. There are one bug in vaadin 7 that cause the
uncorrect restore of FastView when using the restore button of FastView
(when using the toolbar's restore all is ok). In stable version of
vaadin that should be fixed (maybe we can find workaround for this
earlier).
2. Trimbars ported.
3. Bugs in PersepactiveStack fixed.
4. Styles ported to vaadin 7 (.v-app added). There are a log of work to
complete porting styles to vaadin 7
