GDPS Compatibility (kinda)

I've started work on making GDBrowser compatible with GD private servers :D
Currently a few things (comments, leaderboards, etc) are broken but other than that I'm kind of getting there.

This commit mostly just makes life easier for people who want to fork GDBrowser for their private server
- The endpoint (e.g. boomlings.com) is now set in index.js
- Added gdpsConfig.js, where you can tweak small settings in case your GDPS does stuff weirdly
- Small tweaks to the code so the weird GDPS responses can be correctly interpreted
- secretStuff.json is no longer mandatory

If you're able to help me out with this project, PRs are appreciated :D

- Removed Herobrine

 Sorry for my messy code. It's why I was skeptical about making this open source, but you know what, the code runs fine in the end.

+## Using this for a GDPS?
+I mean, sure. Why not.
+
+Just make sure to give credit, obviously. Via the bottom of the homepage, the credits button, or maybe even both if you're feeling extra nice.
+
+Obviously, GDBrowser isn't perfect when it comes to GD private servers, since both requests and responses might be a bit different. Or a LOT, as I learned.
+
+You can tweak the endpoint (e.g. boomlings.com) in index.js
+
+You can also check out `/misc/gdpsConfig.js` to tweak some additional GDPS settings such as whether to decrypt level descriptions or if timestamps should end with "ago"
+
+GDPS compatibility is still a HUGE work in progress, so pull requests would be greatly appreciated if you manage to make any improvements!

+# Folders

+GDBrowser has a lot of folders. I like to keep things neat.

+Most folders contain exactly what you'd expect, but here's some in-depth info in case you're in the dark.

+## API
 This is where all the backend stuff happens! Yipee!
 
 They're all fairly similar. Fetch something from boomlings.com, parse the response, and serve it in a crisp and non-intimidating JSON. This is probably what you came for.
