Small feature suggestion: arbitrary filter categories

[brimby]

My idea is that each user can easily create their own filter categories for ES by simply adding them to gamelist.xml. So basically in gamelist.xml you'd do something like:

<gameList>
    <game>
        <name>Game Example 1</name>
        <genre>Action</genre>
        <region arb-filter="true">Japan</region>
        <length arb-filter="true">Long</length>
        <difficulty arb-filter="true">Medium</difficulty>
        <theme arb-filter="true">Dinosaurs</theme>
    </game>
    <game>
        <name>Game Example 2</name>
        <genre>Adventure</genre>
        <region arb-filter="true">Europe</region>
        <length arb-filter="true">Long-ish</length>
        <difficulty arb-filter="true">Wimpy</difficulty>
        <theme arb-filter="true">Western</theme>
    </game>
</gameList>

And then in emulationstation you would go to "Filter Gamelist" and your arbitrary filters of "Region", "Length", "Difficulty" and "Theme" would all be there with your values ("Long-ish", "Wimpy", "Western" or whatever you created). It would work basically exactly like how "Genre" works where it collects whatever values exist in each genre tag in gamelist.xml for use in a filter, except that you could have full freedom in making your own filter tags. I think that would be a lot nicer than having everyone have to agree on which new filters get added, if that would ever even happen (I want region!!!).

What do y'all think?

At first blush this sounds decent. I'm not sure how ES is coded, but flexibility is almost always a good thing.
