custom filter: Improvements

[dasistwas]

Current status: When in the view settings the tag '##pagingbar##' is included and I use a custom filter, then the paging bar does not show up due to lack of limitation to set entries per page.

• In custom filter settings add possibility to define per page setting like on the regular filters
• Make sure paging bar shows up
• Display number of filtered entries / total entries
• Sort order is not respected. Make sort order work again.

Steps:
I create a view with pagingbar and custom filter
I select 1 in the Per page menu
I search for something in the customfilter - works
I sort by some field, works also
I click on the pagingbar page 2 and filters are gone - fails

So here pagingbar actually shows up when using customfilters but does not work properly. Am looking into that.

I've been working on this for a few days now without much progress. Customfilter is in big parts incompatible with filter and pagination does not work as expected bc. data is not passed.

To get the number of total entries we need to build a separate query without customfilter, this is a huge overhead.
