Subject: Fix API to use the search object

Since the internal of the listWhere method was changed, the API wasn't working. It was still calling the method with the old parameters.
I didn't test it but now, it should work.

Subject: Fix entry DAO query usage

I did not fix the call in the previous commit. I hope this one is the last change needed.

We definitely need a templating engine so we could use the same controller to output different things.
This will remove code duplication between the api and the web interface.
It will allows us to build other type of api, and also refactor the rss feed as a different view of the same dataset.

Subject: More PubSubHubbub

https://github.com/FreshRSS/FreshRSS/issues/312
Show whether PubSubHubbub is enabled in the Web interface of feed
configuration.
When PubSubHubbub is used, do not pull refresh so often (hard-coded to
max once per 24h for now).
Improved logic for lease renewal, and some detection of lease problems.
Updated read-me and changelog.
