Added 1280x720 screen resolution to the graphics settings.

- Improved Performance: Create new LODs and adjust their distance; Lightmap UV's retouched and improved; Lighting retouched. Of course, it is important to remember that the graphics configuration depends on the PC and that what consumes the most are Vsync and Shadows. I also specify that I have NOT optimized the particles of the Explosions, so when there is an explosion the performance DOES decrease.

- Easier Final Boss: Normal attacks take less health; Spin attack takes less health; The boss recovers less health. Now it must not be very difficult to defeat the Final Boss, but remember that many times it is preferable not to stop firing even if there is little power in the weapon than a lot of power with a long reload time. Use your own strategies.

- Fixed an issue with entering the room on the F1 floor of the East Area that would sometimes not open when pressing the "E" key.
