Updated sign handling to be more efficient and faster
Added tab complete for commands where it's possible. So now you can tab complete things like question categories or question rewards, player names and similar things.
Fix for top signs showing list in decimal format when it should not, this was the case when showing list by answers.
Added option to display top list in holographic displays, this requires you to have CMI for it to work. So now you can use /tryme holocreate qmode answers desc 10 which will create hologram up to 10 lines (max 40) which will automatically update with new information if someone answers correctly to a question from that game mode. As holograms can be longer then sign lines, we will show place number, full player name, count of answers, average time it took to answer and players personal best.
