pageinfo() test no longer required, unit test committed elsewhere and
verified against both previous and updated versions of pageinfo() fn.

basicinfo() and mediainfo() tests separated each into their own test
file.

For some reason without position: relative the search button is hidden
in rtl languages.

The previous fix in e38f3066 fixed this
bug only in tb_formatln.

unit tests for pageinfo()

Change function call from actionOk into actionOK (correct name)

This adds $INPUT in all places where it was still missing and available.
$INPUT is now also used in places where using $_REQUEST/... was okay in
order to make the code consistent.

This reverts parts of the changes from #154: Before merging the pull
request, a depth of 1 returned just the pages in the root namespace.
With the changes in the pull request, a depth of 1 also returned pages
in subnamespaces of the root namespace (as it was also tested in the test case).
This reverts this part of the changes and a depth of 1 returns just the
pages in the root namespace again.

In the case of a failed authentication initialization, the
authentication setup was simply continued with an unset $auth object.
This restores the previous behavior (before merging #141) of simply
returning after unsetting $auth. Furthermore this re-introduces the
check if $auth is set before checking $auth and removes a useless
check if $auth is true (could never be false).

changed nonexistant actionOk to actionOK

IE9 send different HTTP_ACCEPT_LANGUAGE header on ajax request. This causes different results from auth_browseruid. This patch removes the HTTP_ACCEPT_LANGUAGE from the browser id calculation.
