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']`

Result:
The module will show as many as maximumEntries for EACH calendar
Expected:
The module shall not show more than a total of maximumEntries, regardless of how many calendars I specify

current weather. It uses the configured units (metric, imperial,
default) to determine the sign.
