MvM Snowfall

MvM Snowfall RC2

So after more than a year of being neglected, I finally decided to fix some things.

-I should have fixed giants getting stuck in the right spawn.
-Upgrade station no longer breaks after wave failure.
-Removed 3d skybox because it was just ugly.
-Along with some correct texture alignments.
Map changes:
-Out of beta
-Several optimization changes
-Changed the 3D skybox a bit
-Added some finishing touches here and there

Still struggling to make a mission for it though. I'm currently out of inspiration.
Things done:
-Slight adjustments to the nav file to make bot navigation more smooth.
-Slight adjustment to tank path.
-Increased performance of the map.
-Repacked the map, didn't have time for this during the jam.

To do list:
-Make my own mission.
-Polish the map some more.
-Stuff...
