Add a new column in all reports for % percentage of visits

Removing the 'url' metadata column from all datatables coming out of the "Actions.*" APIs. Tests output show that it works and will not regress in the future.

refs #1816 do not calculate totals in case apiModule or apiMethod is not set. This means basically "do not run datamanipulators". It happens for instance when flat is enabled and it tries to load all subtables, there should be no need to calculate the datatable for each of those then

         * When the cron to run archive.php is executed, it fetches the list of website IDs to process.
         * Use this hook to add, remove, or change the order of websites IDs to pre-archive.

refs #1816 make sure we get a date string and not an array of date strings in case for instance when handling period=month

refs #1816 make sure apiMethod and apiModule is set. This seems to be not the case for instance if flat=1. Reproduceable if clicking flatten in custom variables

Fixes #4320 Run the getMinTimeArchiveProcessed init function even if force archiving is enabled via debug setting
