Update 2.0.266. Improved server and client optimization

Deep profiling of the server was done and many bottlenecks were fixed based on the received data. Client performance has also been improved (most noticeable on High and Normal graphics settings).

We will continue to monitor the situation and improve the stability of the game, this is a top priority for us!

Server and client optimization
- Significantly optimized several bottlenecks identified during real server profiling.
- Optimized some textures.
- Very low quality settings now use even less memory.

Improvements and fixes
- The number of dungeons that can be created at the same time is doubled.
- Fixed a critical error due to which, if you exit the game before the grave appears, or without pressing the Resurrect button, the character was not sent to the save point, he appeared near the place of death.
