The Big QoL Update

First of several, probably. This update responds mostly to recent player feedback.

• To minimise the chances of accidentally use modulators in the wrong direction, I've added contextual visual feedback showing the colours surrounding the 2 options:

• The reward for releasing chickens has now been raised to 20-35 eggs, so the average is now 27.5 - slightly higher than the Pullet Pool reward. I will continue balancing this till we have a mix of pullet pool and wild releases that works for the site dynamics.
• Added double click protection on buttons and links that perform significant actions (buying items, hatching eggs, releasing chickens). Previously, the operations were already idempotent, but now you can't accidentally get a 404 error from clicking twice by accident.
• The Pullet Pool will now fill faster based on the number of users on the site (1 more per day for every 10 users).

Thank you to all who submitted their suggestions and bug reports!
