Title: Add functionality to count only specific messages

Currently you can store messages, but you cannot count them!

For example, if you are tracking pageviews, impressions, interactions etc. you want to know how many impressions a certain type has.

I added a new options parameter :message that allows filtering by message. So you can still use the :filter paramater to get for example the unique impressions.
