Mega Update: Chicken search, blocking, and text comments

Lots of recent changes!

• Added chicken search game (thanks to Neotheatre for the idea) and looking to add at least one more game before release. Earn a few egg-xtra eggs every day!
• All profile comments now allow text and emojis. I've implemented a sanitization filter, but the "bad words" list wasn't created by me, so do let me know if it's censoring things overzealously.
• Blocking users should be fully functional now. The blocked/blocking users should appear nonexistent to each other by default. Toggle how users who blocked you appear in your settings.
• New Modulator splicers - change a colour gene once in the chicken's life.
• The ticketing system got spruced up; it now has more features (and hopefully no more bugs).

I feel like the site is getting very close to ready for open beta. Once all core features are in, I'd like to give it a couple of weeks in a stable (not-being-actively-updated) state so that we can catch any remaining bugs. Once I'm sure it's ship-shape...it's time for open beta! Everyone who's currently on the site will get a special reward for helping me out with debugging and to make up for anything you may have lost due to bugs.
