QA-0-1-5

This post is intended for QA testers to read about the changes made to the latest QA test release.

- Temporarily removed quit button. There is an issue where the event is not being recognised after disconnecting from the lobby or a game server, thus stopping the button from working as intended (this can be demonstrated by running the game and clicking the close button - it will work. However, if you go into a lobby or a game, it will cease to function).

- Physics raycasting changes including a new line renderer for the default weapon (laser).

- optimisation of scene objects and network functions.

- Changes to the main menu layout.

- changes to network send rate for player movement.
