FIXME

1) Check feed duplication on runtime.
    When feed is valid and is not yet in the database it is
    posible to send a batch which would result in duplication.
    Consequently, it might result in database lock error upon
    feed removal attempt

TODO

1) SQL prepared statements

2) Machine Learning for scrapping Title, Link, Summary and Timstamp

3) Support MUC

4) Support categories

5) Default prepackaged list of feeds

6) XMPP commands

7) Bot as transport

8) OMEMO

9) Logging

10) Default feeds (e.g. Blacklisted News, TBOT etc.)

11) Download and upload/send article (xHTML, xHTMLZ, Markdown, MHTML, TXT)
    Use Readability
