Add more Filters

I was caching with a iPhone/Cachly user recently and they had an amazing list of filters in that app. Here are some screenshots from Cachly:

We were in an area with a lot of hides by two geocachers and we were struggling with finding their caches. So we used the filters in Cachly to exclude their caches to figure out where we could go next to avoid most of their caches.

It would be nice to see some/all of these filters in GCDroid (those that don't already exist)
