Derailed A24

Removed passage directly from spawns to point to prevent spawncamping;
Changed mid significantly, few times;
Mid building was redesign a little;
In other words, it's "a whoole neeew woooorld"

• Removed old entry to lower story of pointside building, replaced with new one, put more emphasis on attacking point from there
• Moved point from middle battlegrounds area to upper one
• Reduced ability to spawncamp from upstairs area
• Added soundscapes
• Finished 3D skybox, complete with dynamic effects

Messed up spawns, blu info_player_teamspawns were set to red team

Forgot to enable respawnrooms, also big thank you to Cartfridge for name suggestion!
