Mastodawn

I've changed quite a few parts on joinmastodon.org/servers today in response to the feedback from the past week. In detail:

You can now filter by region, type of legal entity, and sign-up speed. Added note about why the topics filter exists. Changed tagline.

"Get on waitlist" has become "Apply for an account" for servers that manually review new sign-ups. Removed total user count from cards.

@Gargron is there a reason some servers have been removed? (e.g. i originally discovered tech.lgbt on that page, and it's no longer there!)

@tarajdactyl @Gargron Guessing they requested to be removed due to increased load of new accounts.

@ailnoth @Gargron that makes a lot of sense, thanks! the server was certainly getting hammered.
