RCFilters: Minimize url string

RCFilters: Minimize url string

In order to minimize the URL query, we use a base representation of the
parameters as if they were all '0' or '' and internally expand on it.

- Only display parameters with a value that is not empty or '0' in the
  URI. Any parameter that is missing from the URI is presumed to have
  an empty value.
- Stop pushing defaultParameters everywhere. Default parameters should
  only be considered either on load (when/if needed) or when the user
  actively requests for them.
- Minimize parameters to the URL, and expand when reading into the model.

Similar to using base filters, we can use a representation of base
parameters to make the URL small but the representation all-encompassing.
