Patch for several issues

Delinting using http://www.coffeelint.org/

Adding throttle parameter to config (but set to false) to highlight
that it exists

Adding tripple mustaches to deal with issue #116

Adding namespace logic to anon and config to support issue #118
This allows filtering out edits in talk namespaces etc,
if namespace is left out of config all namespaces are accepted

Added logic to disregard @metadata entries in ranges to support issue #115
this allows source, dates etc. to be added to the ranges
