Keep query params during redirect to headpage

As discussed in Issue #1454 dokuwiki currently "forgets" additional
queryparams when redirecting from devel: to devel:start

Example:
https://www.dokuwiki.org/devel:?foo=bar
should result in
https://www.dokuwiki.org/devel:start?foo=bar
but actually results in
https://www.dokuwiki.org/devel:start

This commit fixes that behaviour.

Fixes #1454

Add an ACL check in page_findnearest, fix #1369

This means that templates that use this function will no longer display
pages like sidebars that can't be accessed by the current user.

Remove error supression for file_exists()

In an older version of PHP a file_exists() call would issue a warning
when the file did not exist. This was fixed in later PHP releases. Since
we require PHP 5.3 now, there's no need to supress any error here
anymore. This might even give a minor performance boost.
