Wallets: Re-Add Circle.com To The Wallet Page

[harding]

Opened at the request of @ywecur in pull #700, this pull request re-adds Circle.com to the wallets page with the same content it had previously.

Circle was removed because it did not implement HSTS, but it does now:

$ curl -s -D- https://circle.com/ | grep Strict
Strict-Transport-Security: max-age=15552000

LGTM. In the absence of critical feedback, this pull request will be merged on February 6th.

Thank you @harding , I much appreciate your help!

I thought Circle didn't want to be on bitcoin.org? Are they okay with this?

@luke-jr according to @saivann in this comment:

OK some quick update; apparently if some people really want to add Circle, the contacts I've talked to don't seem to have any serious issue either way.
