Prettify query params

[JostCrow]

This is a small change that lets you prettify the query parameters.

You can still use the original parameters to filter.

I hope that this is something that you are interested in.

I was actually thinking about something like that except at filterset layer vs DRF integration. Doing in DRF will obviously only prettify things only for DRF whereas this seems like useful addition for other usages. Haven't decided though on good approach for doing that though. Would prefer to keep things declarative:

class MyFilterSet(ModelFilterSet):
    class Meta(object):
        model = Foo
        prettify = {..}

but that will not work for regular filtersets and this just looks ugly to me:

class MyFilterSet(FilterSet):
    foo = FooFilterSet()
    prettify = {...}

I agree that this needs to be a global option instead of for DRF only.

With the filter part, I don't know what would be best yet. Since I did not dive into the code yet. This was just a quick build and it needs to be improved. I will have a better look at the code for a better solution.

I believe this feature is now provided by #66
