Added the function of focusing on the word you search. Two methods were added. The first one is searchResultSelection, which parses a JSONObject passed from LOK and focuses on the text selection. The second one is moveViewportToMakeSelectionVisible. It handles well both documents and spreadsheets. I also tried to add a search not found toast message. Also corrected a typo.
