[Feature] add new filters

[blawar]

To compliment #248 , new filters could be added.

Below is an example of the json data available to be leveraged for a filter. But what jumps out is adding: languages, rating, number of players, ratingContent, and category. Maybe a search filter to search name, intro, and description though I am not sure how useful that would be.

To add a new filter, you: a) add a new property for it to Config.Download: https://github.com/blawar/nut/blob/master/nut/Config.py#L699 b) add a line somewhere in Config.load to parse and load the json value: https://github.com/blawar/nut/blob/master/nut/Config.py#L445 c) Then apply the filter in Title.isActive: https://github.com/blawar/nut/blob/master/nut/Title.py#L552
