When the current page id ends with ":" (or "/" with useslash enabled)
DokuWiki tries to find the start page of namespaces automatically and
then redirects to this page. The target of the redirect is always the
show action regardless if the current request contains another action or
is an ajax request. In practice you can get this problem when your
search query ends with ":" (e.g. because you want to match a namespace),
then you are redirected to the show action.

This change completely disables the redirect when $ACT is undefined or
the current action is not "show".

Fix page tools display with images disabled FS#2634

alternative fix for FS#2734

This fixes the image display in IE7 with the disadvantage that now in
IE7 with images disabled the text won't be displayed anymore.

This makes the pagetools in non-hover/static/active-mode use another
image replacement technique that falls back to the text when images are
disabled. Furthermore this fixes the :focused-display in IE7 by using
:active, too.

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.

FS#2724.  fix 'are you sure' when using refresh after using tpl_actiondropdown

Fix double encoding in rss syntax FS#2731

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.

remove security token from tpl_actiondropdown - its not necessary, we're not posting any system change
