This fixes plugins that expect that they can change the global $ACT
instead of $event->data in the ACTION_ACT_PREPROCESS event.

This make the whole route a little bit uncleaner but would increase
backwards compatibility.

I'm not sure how widespread the problem is and if adding this is a good
idea.

This should recreate the behaviour prior to #1933, where the event was
triggered for all ACT values. Some plugins, like edittable, depend on
the functionality.

Since the hid is optional, it must also be optional in the regex. Also
this commit introduced named capture groups to make it more obvious
which part of the regex captures what.

Also there is now an explicit hid generated for tables, to enable
jumping to the correct section after finishing editing.

This was broken in 2571786c or #1966
respectively.

Known Issues:
* since both title and hid are optional, a hid may be misinterpreted as
a title if the title is not generated.

Add parent namespace pattern replacement

Exits during testing will break the whole test suite. It makes more
sense to throw an exception in that case. The exception's stack trace
will help to debug the actual problem

No globals required anymore, somewhat more general approach to sending
data to the test system. Clean access through keys.
