Use google's Predicate class instead of samskivert's.

- It's probably "more" standard, and maybe when they finally add Predicate
  to java.util, it will be based on google's implementation.
- Unfortunately this is a little less efficient at runtime. The samskivert
  Predicate can filter into a new Collection that knows its size, google's
  code just returns an Iterable that is a *view* on the Iterable passed
  in, so it doesn't know how many elements are in it. When we copy it into
  an array, a List is first created to receive all the filtered elements
  from this view, then that List is turned into an array. Oh well, it's
  less lines of code here in this class thanks to Google's fun libs.
