URL syntax is &formid=xy (not &fabrik=xy)
Removing wrong "fix" for module ordering overrides, which was
incorrectly adding order icons on those columns, rather than just adding
to the main getData ordering.

Added submission debugging, so &fabrikdebug=2 will bypass any and all
redirects, so we can see profile info, etc.
Added profiler marks at start and end of main form model process()
Making order plugin working when list has joins

The limitation that enabled list order plugin only with one single "order by" element prevented reordering also in case when the list had joins (even with a single order by element).
At the same time the lists with joins often have to be ordered by multiple elements as we may want to display the joined data always in particular order (let's say composer always the first, lyricist the second etc).
