[feature] :title meta-data suport for feeds

[groks]

Some feeds have long, uninformative, or no titles at all. There's an issue for feed renaming (skeeto/elfeed/issues/78) and support has been added for the :title property on feeds.

How about this feature for elfeed-org: if you use an Org link to define the feed then use the link description to set the :title property.

* Feeds :elfeed:
** [[http://example.com][This Becomes The Feed Title]] :atag:
** http://example.com/use-default-feed-title

I like this suggestion. When I have some time I'll certainly implement this.

+10 great feature

I thought it was a good idea too, so I had a go at it and have submitted a pull request.

Thanks a lot for submitting your PR! I'm afraid it did not pass one of the tests though. Could you take a look at the test results and try to solve it?

[Kungsgeten]

I've commented on the PR, but I've modified your test a bit and it seems to work now.
