Resolves#1071
`prohibitedWords` config parameter is an array of words. If set and case insensitive greedy match is found anywhere in the title then that newsfeed item will not be displayed. Readme updated with instructions.
Users should be careful on the words selection as careless setting may remove many or all items from the newsfeed. Some obvious mistakes like `space, comma, dot` etc. can be prevented programatically, but I left it out of this PR
Example:
with `prohibitedWords: ['dodgers']`

Many feed descriptions end with with a link tag to the actual article
online (see http://www.deutschlandfunk.de/die-nachrichten.353.de.rss,
for example). The mirror news description looks strange with this tag in
the end.
I have added an option to remove the tag from the description and
updated the readme.md accordingly.
