In the borders tabpage used in Writer's "Borders" tab of the "Format" -> "Paragraphs" dialog, don't always send AccessibleStateType::FOCUSED events for a border when it is selected. Only do so when it also receives focus, not otherwise. Add a bool param to FrameSelector::SelectBorder to indicate whether or not the event should be sent. For the case of clicking one of the options in the "Presets" section handled in SvxBorderTabPage::SelPreHdl_Impl, focus remains on the selected item there, so don't send a focus event. This prevents misleading screen readers about what widget/object is actually focused. The logic in SelPreHdl_Impl was more or less there already, just commented out...
