Updated the Support Angry Beanie page

Hi all,

Just a quick note that I've updated the Support Angry Beanie page to be a bit more not crap.

I've also added links to Redbubble for Angry Beanie merchandise and information about our Patreon account (should you be so inclined).

On the fundraising note, I've added our first target on Patreon. 

I'm aiming for $50 a month to help offset the costs of running Angry Beanie. This includes things like Linode rental, Skype costs and starting to build up a bit of a gear fund.
