Demo version even hotter fix 02.09.24

Gameplay videos of our game finally started appearing on YT, which helped us finding new things, that we have overlooked.

• Fixed FOV slider's description. * Fixed the level ending screen and added an ability to restart the level without returning to the main menu (such propmt appears after 3 seconds). * Added UI scaling for screens wider than 16:9 (tested on 24:9 virtual aspect ratio). * Added juicy giblets to the main menu's background. * Fixed a critical bug in EXPLORER OVEREXTERMINATOR achievement's trigger. Now you really have to show me some skill to achieve this achievement. * Balanced weapon swapping for reload animation cancelling. Now it's possible to swap the gun only if it's not playing animations of drawing or firing. You can still swap while reloading (and this feature will persist). * Added spawning of 10 more medkits at the central district at the beginning of the mega-wave.
