Title: Use Apache Commons CollectionUtils

This pull request introduces Apache Commons CollectionUtils, as we added StringUtils before.

The CollectionUtils library is actively maintained and has been field tested. Notice in the first of those two commits how we got something as simple as "isEmpty" wrong when trying to reimplement it (we didn't have Proguard then).

CollectionUtils also brings nice iterators, bidirectional maps, better typed collections utilities and so on. See http://commons.apache.org/collections/ for more information.
