Defection update #1: 2 new maps, improved pictures, inviting friends and more

Hello. The following changes were made to the first Defection update: - 2 new maps Ice peak Steam post image Snow map for Conquest Mode Ruins Steam post image A simple map for the DM, TDM and Scavenger modes - Added the ability to invite, or join friends on the server. This can be done through the Steam overlay (Shift Tab), or in the main menu of the game in the pop-up window with a list of friends, which is located in the lower left corner - When creating a server, the ability to add bots is implemented, their number will depend on the number of players on the server - In case of respawn, the player will now act invulnerability for 4 seconds, invulnerability does not protect against damage from meat grinders or falls from a height. - Minor bugs fixed (new ones added) P.S. Communicating with the community, many players are faced with desynchronization with the server (the interface disappears, a long response when changing equipment in the interface, etc.). Therefore, I decided that the next update of the game will be devoted to refactoring the code. I will correct the found bugs, I will simplify the technical side of the game modes. Perhaps, as it rethink the mode "Scavenger". To the maximum I will try to optimize the network code. In general, the game will be better, the game will be more fun. At a rough estimate, the next update will be released in mid-May. After it, I will start updating melee, new skins and of course weapons.
