- Split entity code Lua files by realm (server, client, shared)
- Use $pp_colour_inv for color inversion
- Remove pp/texturize/invert.png as we now use $pp_colour_inv in its place
- Fixed an issue where hitting the ball perpendicular to an axis it's locked to would massively slow the ball down
- Fixed a bug where ball damage events may have accidentally been applied twice
- Use util.AddNetworkString in entity Lua file initialization instead of every time an instance of the entity is initialized
- Use better hook initialization and removal (ent identifier which uses IsValid check)
- Color invert now only applies to players within the entity's PVS instead of all players on the server
- Added some additional IsValid checks to prevent errors
- Add small screen shake effect whenever the ball collides with a wall
- Hitting the ball now 'locks' the player (freezes them & gives them temporary godmode) until the ball is unfrozen
