Suggest bounties for the last few issues opened by the user [$5]

I think it would make it easier (and more tempting) to place bounties if bounty source read my github activity stream when I logged in, and displayed buttons for placing bounties on the last few issue I opened or commented on.

There is a **[$5 open bounty](https://www.bountysource.com/issues/995804-suggest-bounties-for-the-last-few-issues-opened-by-the-user-5?utm_campaign=plugin&utm_content=tracker%2F47&utm_medium=issues&utm_source=github)** on this issue.
