Title: Adding additional catalog session parameters to category's cache key

CacheObserver already factored in the category's product limit but was missing other dimensions that can be used to create a more accurate cache key particularly for product lists. These parameters were pulled from the `Enterprise_PageCache_Model_Processor_Category::$_paramsMap` property since they are used to generate the page id within that class.
