    Add attributes to filters and fix registry The filter registry as implemented was too primitive to actually work once multiple filters were coming into play. This expands the implementation of the registry to handle multiple prioritized filters correctly. Additionally, this adds an "attributes" field to a filter that makes it really really easy to implement filters that are based on one or more attribute values. The lookup and even simple value checking can all happen automatically without custom filter code. Lastly, with the registry improvements, this fills out the filter lifecycle callbacks, with initialize and shutdown callbacks that will be called before the filter is first used and after it is last invoked. This allows for system-wide initialization and cleanup by the filter.
