Sakura a8_fix2

After nearly 5 years of waiting a new Sakura fix update has finally arrived.
Changes:

• Recompiled all custom models to add missing model files to prevent client crashes with low model and texture settings
• Packed the nav file into the bsp
• Heavily improved map visibility optimizations
• Reduced lots of unneccessary brush surfaces
• The grass displacements are properly sewn, the cutting lines are gone now
• General texture file size compressions
• When copying the abandoned area and the ghost zone as a template for the Forest Realms map I accidentaly squished the whole area. This part has been stretched back to the previous height.

Due to nostalgia reasons there is no new content and there are no visible changes on this map. In terms of map design, models and sounds the map itself is still in 2019/2020 mode and probably won't get any more content updates.

Changes:
- lighting fixes
- compressed map size
- the soundscape volume can be adjusted in the TF2 music settings

Changes:
- added lower gravity to the space room
- more map details
- fixed a problem regarding hitboxes of the Star Wars ships & fixing their lighting
- added new second credits room
- added ghost underworld
- added a darker version of the main room
- you can spawn Merasmus or Monoculus every 15 minutes
- new teleports
- new music

Changes:
- improved lighting
- func_details and compressed wavs (the map has a smaller size now)
- soundscapes are now also in the spawn rooms
- added death pit
- added second space room
- added arena stuff to the blue lava room
- new credits room
- new music

!!! some of the star wars ships in the second space room had an error when porting and their hitbox is broken and is far longer than it's supposed to be. That's why the room is a lot longer and it's covered full of lights to let the ships glow in the dark. One of the ships is still dark; I'll try to fix this in the next version, now it's covered with fire particles.

changes:
- removed the endless stairs and replaced with a blue lava zone arena
- added particles
- added sound effects "another happy landing" and "hello there"
- added more details to the map

Updated download source. The version of the map should be a5.

As always, you can suggest improvements or new ideas : )
