Set an option to only show quotes that aren't 'Nerdy'

[Painatalman]

Some items are only funny to people with knowledge on subjects that can be labeled as 'geek', such as wrestling, movies or videogames. Such items may alienate some users that may still find other quotes interesting.

Thus, it would be interesting to set a mode whese items are discarded.

In the future, we may even include tags in quotes, to categorize them.
