Exclude images by tag

[yellowbluesky]

Should be simple

Will just integrate be more lines in filterRanking() and filterAuth(). Break it out into a separate function?

[yellowbluesky]

Will need testing to see if more than one tag search term works, and the syntax (comma or space delimited etc)

Possibly open a new issue to track this

Will need a Preference, allowing the user to pick what language the search terms are going to be in.

Languages to have are English, Japanese, and Chinese for now. I'm not sure what other languages Pixiv supports, and what their code are. Preference can be a simple DropDownPreference.

As to how to organize it, can PreferenceCategory have sub-PreferenceCategory's? Easy to test when I have the time

Language selection added in 8aafa71

Tag input not yet implemented. I'm thinking of having an EditTextPreference, with users entering a comma delimited list of tags to exclude

Also need a way to pass Accept-Language to PixivArtService, perhaps pass them a partially formed Request with only the 'Accept-Langauge' field filled?

ArrayAdapter in a ListView would be a much nicer way of managing tags
