More reliable and better for large group play

After hosting a laser tag party for my son, we have made a number of improvements aimed at making the game more reliable and easier for dedicated server games.

-Made player settings dialog scrollable so you can get to all of the options on all devices
-Allow server to specify what shot modes are available for clients to select (auto, burst, single)
-Improve hit filtering by using the shot ID data field discovered by Ted Milker
-Add team score totals to the scoreboard in team games
-Allow reconnecting the same weapon if weapon disconnects in the middle of an active game
-Allow a dedicated server to change settings for all players when no players are connected (bugfix)
-Add an option to allow players to join or rejoin a game that is already in progress
-Add a start game button to the dedicated server so that the server can start the game
-Allow dedicated server to set and change firing mode for clients (indoor, outdoor with and without cone)
-Add an option to the dedicated server to disable most client settings making the UI simpler for clients and preventing unwanted client changes
-Allow clients to change their network player name while in the game lobby
-Once a client pairs with a blaster, you will then have a "Reconnect Same Weapon Only" button that will attempt to reconnect to the same blaster as before and ignore any other blasters. This option should make it easier to re-pair blasters without having to pair only one blaster at a time.
