(v1.4) Purge a bunch of legacy/unused stuff

See merge request KartKrew/Kart!633

Aren't used and definitely should not be in here anymore

Blast from the past, buuuut let's trim the fat here too.

Written in VB6. Superceded by better tools and also probably not even
buildable anymore.

SRB2 no longer works with 1.2 or Dreamcast so these are irrelevant

Superceded by far superior tools

Once more, SRB2 no longer works on DOS so this is irrelevant

SRB2 no longer works on DOS so this is irrelevant

Also unsupported and nonfunctional

This thing is ancient history and also depends on FMOD.

Technically just removes one event that causes the crash instead of the actual crash, but I tried attacking it at the source and it's some nasty, nasty stuff...

And add a little extra to the comment for anti-footgun insurance.

* New version number.
* New MODVERSION.
* New asset hashes.
* Disable patch.kart requirement.
* Remove the request to modify CMakeLists.txt, because that got revamped and grabs the version number from elsewhere now.

Located by my new compiler! Also a nice, simple test commit for my new Git client...

Also, I fell for the copypasted code bait CLASSIC, so now all instances of the Ruby are decoupled from FPS cap.

Instead of reverting kartspeed on invalid set, prevent it from being set in the first place, just like Encore! Should resolve desync.

They were skipped because I didn't expect anyone to use them as they're simply leftover SRB2 assets, but Kart Airlines surprised me by using them as pushable track hazards.

The part of HOSTMOD ministats that I wanted. Can go back to ms using the pingmeasurement cvar.

If Tyron wants to bring ministats fully in I think it'd be better to bring its ideas to replace the current HUD instead, ideally using the existing ping gfx, so they should bring it up with Oni

Print rules in menu and in console

Better bans

See merge request !285

Catch several ways ban.txt could be malformed by a well-meaning server host, and report it back via the log.

Fix MusicChange lua hook returning some values incorrectly

See merge request !287

Update HMS version to 2.2.

Fetch the rules when master server cvar set. Print rules
in console when server register. Display the rules in the
menu when entering the server hosting menu or when
changing the advertise cvar.

* Warn the user when an incompatible ban.txt is being loaded, and stop early.
* Don't inexplicably assign as a boolean, you bafooligan!

Fix an issue where if the last line of an M_StartMessage was the longest, the box width wouldn't account for it.

* Fix some bugs.
    * Reset bannode information properly, fixing being unable to join your own server.
    * Write to the buffer before saving the kick/ban reason, rather than after.
* Improve the print output for the `showbanlist` command.
    * Includes username.
    * Includes remaining time as seen by a kicked joiner.
    * Hides expired bans.
* Improve the messages for ban/kick related refused joins.
    * Replace the Reason with the actual admin-provided reason for refused connection.
    * Replace the "Server refuses connection" header with "You have been [banned/temporarily kicked] from the server", the previous given Reason.
    * Fudge the time reported for temporary kicks so that a user is encouraged to return slightly after their tempkick ends, rather than before.
* Add an extra newline to the M_StartMessage for being kicked/banned with a reason provided.

Create a single struct for bannednode and bannednodetimelft, and use the matching ban ID inside that struct.

While this commit does not increase the visibility of ban reasons, it makes this possible later.
