use wl() when reditecting old style search url

fixes #2546

renamed ActionRouter::checkPermissions to checkPreconditions

As discussed in #1933

shortened new search configs

shorter names are more in line with what we already use, makes less
layout problems in the documentation and is easier to type when telling
people about it.

refactor: rename dta and dtb parameters

They are now named min and max respectively, which is hopefully less
cryptic.

fix(search): don't search for current page if submitting empty form

Pressing enter in the small quick-search-box while it was empty resulted
in a search for the current pageid.

refactor(search): provide before/after arguments to search event

This way they can be cleanly influenced by the plugins instead of having

This way we do not loose the context of the current page. Further, the

Further redirects exist for the old urls, so bookmarked searches etc.
should mostly keep working.

feat(search): add config options to adjust default behavior

This adds two new config options:

`search_limit_to_first_ns`:
Limit the search to the current X namespaces. When a search is executed
from a page within a deeper namespace, the first X namespaces will be
added as filter.
Possible use case could be with language namespaces to ensure that the
default search is initially within the current language.

`search_default_fragment_behaviour`:
Option to specify the default fragment search behavior
