BUILD 3900 - Christmas 2021 update, minor QoL fixes

This is a minor update for the holiday season bringing the usual Christmas cheer along with some minor QoL changes and an updated CTF map cycle.

We still plan on a major update in the coming weeks. Due to delays we preferred pushing a minor build before that happens. As a reminder, short term plans include reviewing, testing and pushing the following changes:

• some balance changes from Bunnie's CTF Rebuild project, such as faster building during build time, more coin gain from combat, faster hitting on player-built blocks, sawjump removal. If you're interested, you can read more here: https://rentry.co/rebuild-prs (not everything may be added)

• raycasted slashes (Doors will no longer makes builders immortal at certain angles - this led to the frustation of many knight players)

• 360 degree trampoline rotation
