Too much shit to explain, read the diff (you should anyway!)
Very sloppy, expect lots of fixes
TODO: SOC it all, separate "active odds" table, how to handle alt items
* The bubble remains inflated after holding the button, and slowly deflates
* Popping the shield now gives you flashtics, in addition to the speedboost
* Popping it also makes you invulnerable to proxmines!?
* Getting hit by an item while the shield is deflated protects you from
JUST the spinout exactly ONCE, geez, think of the poor D5 players
* Players can be bumped by the inflated shield again, but it's very weak
* Bumping players with a deflated shield depletes half its HP, inflated
bumps cost the same as other bumps
* Race odds now use 16 tiers and are intended to be balanced around 16 players
* DISTVAR has been increased to 2048 to match the new tier capacity
* Race odds now use a max-75 scale, with the x4 multiplier in calcs being used only in a battle odds context
Bot logic is now handled exclusively by the server, now in the actual game
loop code, rather than during ticcmd generation. No TICCMD_BOT needed!
botdata_t has been added to store any variables that clients don't need.
Behavior differences:
* Brakedrifting actually works now... to the detriment of the bots
* Respawn triggers 1 second sooner (and actually causes braking)
* No longer spams respawn when a track lacks waypoints
* Turning might be less responsive?
`botvars.turnconfirm += cmd.bot.turnconfirm` is gone... who knows
* No longer affected by timescale
Plus, no more outdated or copy-pasted comment blocks!
