Links to easy tasks from OpenHatch

Hi guys,

FYI - our Easy Hacks are now linked from OpenHatch's entry-level code
page:

https://openhatch.org/wiki/Easy_bugs_for_newcomers

, which is a rather nice & prominent place. Should we add more
entry-level coding pointers, or change the URLs, let's remember to
keep that page up-to-date.

Cheers,

-- Thorsten
