This reverts commit 3940c519 as
discussed in #1082.

Added file-in-use reference to page

Since the pageid is no longer positioned absolute it clashed with the
sidebar since #1027. this introduces a very simplisitc fix.

This reverts commit 362a4f08.

This moves the message area into content div. The pageid is now aligned
by floating instead of absolute positioning.

As described in the common idioms of the HTML5 spec, mark up navigation as a list inside a `nav` element for better semantics and accessibility.

fixed pagetools being inaccessible on screens lacking necessary height, and aligned them to content when on smaller screens

This moves the template name away from the hook name into the event data (as
the 'tpl' value). Therefore it moves the previous data items into the 'items' sub array.
A 'view' value has also been added to describe in which template file the
event was called ('main' or 'detail').

This way it will be much easier for plugins to consider default cases and
differentiate between main and other layouts.

replace boolean conditional checks on possibly uninitialized vars with \!empty/empty/isset as appropriate

Removed extraneous whitespace to eliminate errors reported by the
Squiz.WhiteSpace.SuperfluousWhitespace sniff.

The old 'default' template was deprecated with the release of the new
'dokuwiki' template (2012-10-13). It is still available in a separate
repository here: https://github.com/dokufreaks/template-default

But no-one in the core development team intends to maintain this template
anymore. So, anyone willing to adopt it is welcome to clone it and make it
your own.
