widgets tab shows old widget example, should reference v2 js

[simonmichael]

The examples at https://gratipay.com/~username/widgets/ should probably be updated to match https://github.com/gratipay/grtp.co#standard-widgets . (I replaced username with project name in my widget (<script data-gratipay-username="hledger" data-gratipay-widget="button" src="//grtp.co/v1.js"></script>) and got a link to https://gratipay.com/undefined/ until I noticed the link to newer widget docs.)

Ping @mattbk. Didn't we attempt this at one point during recent widget work?

I had it working at one point, but it was tossed as part of #112.

Ah, okay. Still live then.
