Updated Proofs.md, Updated Profile-Verification.md

• Created Discord.md, as that social part of omg.lol is getting larger. Mirrored a lot of the IRC page as they are bridged together.
• Updated Proofs.md, to include doing proofs via DNS instead of just the WEB method.
• Added a clarifying link in Profile-Verification.md

Instead of repeating the same information again and again, maybe we could have one page for the "instant messaging" side of omg.lol, and then separate pages for the platform-specific information? I'm not sure how it's formatted at the moment.

There's some wording in Discord.md like "here's some popular channels", maybe this could be "here are the available channels"? IRC can have anyone make their own channels, but Discord doesn't work that way.

@byemc Your suggestion makes a lot more sense. And yes, the bulk of the discord paige is really the same as the IRC page because the two are connected via the bridge. As you said, doesn't really make sense to have both.

For now I just removed Discord.md from this PR
