Make only a single set of recentchanges API calls for incremental updates

[kevinlul]

Currently, the incremental update script is invoked once per automatically-updated category.

The recentchanges generator actually returns all changed pages, not just the one specified by clcategories, which only controls the categories that annotate each returned page. This parameter supports multiple categories combined with the | operator like the other parameters. Therefore, all categories to be automatically-updated can be retrieved in one Python script execution and one set of recentchanges API calls, as long as the output is written out to the correct directory based on the category.

There is maximum number of joined categories supported by clcategories. Pages may be in multiple categories and the categories array in the response should reflect this.
