When entry titles or other fields are used as part of a message box, the string should be properly escaped to prevent HTML evaluation. Right now, this is not always the case (such as the confirmation before moving an entry to the trash).

Related: the "headline" when editing an entry isn't properly sanitized. (See this screenshot.) Seems to use both Groups' names and Entrys' entryTitles, by way of EditEntryWidget::loadEntry's parentName parameter, called from (for example) DatabaseWidget::switchToEntryEdit and DatabaseWidget::switchToHistoryView. QLabels should probably be similarly sanitized.
Fixed by above-mentioned commits.
