- Properly call D_SaveBan after remote bans. Bans are no longer saved in the ban command and instead wait for the actual kick to process, since before they were split between the two, which is what caused the discrepancy.

Better code cleanliness, also makes it easier to add more data to bans later (such as a timestamp for temporary bans)

# Conflicts:
#	src/i_tcp.c

Needs proper stress testing but seems to work.

Fix bumpcode, fix magnet landing (better fix)

Fixes high speed bugs without removing the ability to turn at those speeds. Similar fix to what is in Ring Racers.

The intent is to stop servers from needing to dedicate their limited name/MOTD space to things like advertising `lessbattlevotes`, and to avoid "punishing" a server in visibility for allowing temporary gametype switches. However, this is possibly a controversial change, so I'm doing it in its own commit in case there's a clear consensus to revert.

* A "canon" adaptation of the community-created server option `lessbattlevotes`.
* If set to "None", voting behaves as before.
* If set to "Race" or "Battle". that gametype is considered the preference.
    * The voting screen is always operated from the perspective of the preferred gametype.
    * If you're in an un-preferred gametype, the third vote option will always allow you to continue the gametype.
    * If the preferred gametype is Race and you've just exited a Battle map, Encore may now appear on the second vote option.
* A number of bugs with voting have been corrected.
    * If `kartencore` is on, the third vote option will now correctly have Encore applied.
    * If a custom EXE or malformed packet sends an Encore flag alongside a Battle gametype ID, actively strip it.
        * Just to note, clients do not enter Battle Encore with or without this change - this just prevents a promise the rest of the game couldn't fulfill.

Uncapped

See merge request KartKrew/Kart-Public!276

Makes the displayed FPS more accurate to what it's actually displaying.

Also removed HUDTRANS from it -- stop it fading out during level transitions, it's annoying when I actually want to see the FPS during those bits.

Fixes KartKrew/Kart-Public#10

Was done this way for the sake of an older version of uncapped's timing; now that the new timing is much better, I decided it should remain as close to pre-uncapped as it can be.
