Combine all displayed changesets

[contrapunctus-1]

Brief Description

I'm trying to visualize the changes created in our last mapping party, and also to determine the total number of changes we created.

I'm requesting some way to combine all changesets returned by the filters, to -

1. show total additions, modifications and deletions
2. visualize all changes on the interactive map
