Clean the scene when loading a project is optional. — DomiCard Steam update #1049541

Add a new toggle in the "Control Settings" - "Clean the scene when load projects". If the toggle is on, the whole scene will be cleaned when loading a project. Otherwise, game objects in this scene will not be affected. https://cdn.steampulse.org/steam/asset?u=https%3A%2F%2Fsteamcdn-a.akamaihd.net%2Fsteamcommunity%2Fpublic%2Fimages%2Fclans%2F33334648%2F3c9bb06535609712e3c7a9528672dce0782a3905.png The default setting was clean the scene in Single-player mode, but opposite in LAN and online mode. The default setting, for now, is clean the scene in every game mode. Please be aware of this.
