Fix incorrect request type for image searches

Previously had hardcoded POST requests for all requests that didn't use
the header template (which currently is only the image tab).

Also refactored how the Filter class works. It now requires a valid
Config model to be provided, which is then set up as a class var that
the filtering functions can use as needed, rather than setting specific
values from the config as individual values (which was confusing and
sloppy).

Fixes #561
