several fixes for webclips, linking to pdf/web, fonticon dropdowns. removed sliderbox. reduce uses of scriptContext

fixed web clipping annotations to be in correct spot and not to crash because of using a url that it doesn't have.
fixed pdf/web links to not use anchor from other end of link. because of sharing of GetAnchor global.
added a backup when presbox overwrites a doc's data field.
removed sliderBox.
fixed fontIcon dropdowns to not call click script twice.
removed scriptContext where it wasn't needed which is everywhere except TreeViews.
