Delete singleplayer

This fixes a minor bug where it's completely impossible to play SRB2 when allowjoin is disabled.

How will this work in conjunction with !868 (merged)?

changed the description

Completely unrelated.

Not really. This merge request deletes single-player, but !868 (merged) is something affecting the single-player menu options. Surely there'd be some sort of conflict, either code-wise or just practically, between removing something and changing part of that same thing. Changing it can't be done after it's been removed, while removing it should obsolete the entire purpose of !868 (merged) in the first place, leaving it to preferably simply be closed in favour of this merge request.

Ahahahah you've been fooled, we are not actually removing singleplayer, it was a joke!!!!!!!

:awake:

That does leave the title of this merge request, and by extension commits relating to the merging of this, a lie, however.

Yes, and that's perfect.
