Issue 5: The "delete_counter" cgi argument is not anymore a counter name, but a regexp of counter names.

There is a change in how counter get deleted from the CounterNamesManager.

Instead of just deleting one counter name at a time, the cgi argument that gets parsed in HarvestHandler.java line 68 is not any longer a counter name, but a regular expression that matches counter names.
