Rewrite of the tree manager

This rewrite drops all dependencies on jQuery for the tree manager and
uses modern JavaScript for the drag'n'drop operations. It introduces the
posibility to view the tree as a merged tree of page and media
namespaces (similar to what we do in the ACL manager). This merged view
is often advantageous in wikis where both trees are very similar. A
default view can be set in the configuration but users can switch
between the views on a case by case basis.

This does not change any functionality in any of the other scripts or in
the way how the move is executed. It's a GUI refresh only.

Other parts of the plugin could use a GUI refresh as well (eg. use the
same SVG based icons and drop jQuery dependencies).

optionally move media with page rename #222

A new checkbox allows to move referenced page media along with a page
rename.

This happens only if

* the checkbox is ticked
* the page actually moves to a new namespace
* the page was not in the root namespace
* the referenced media is in the same namespace as the page

feat: Add config to toggle pagetools integration

Having a hard-coded list of templates where the integration happens is
cumbersome, because it requires a pull-request for every new template and
it is somehow the wrong order because the templates should have the
option to create special handling for specific plugins, however plugins
should not have special handling for specific templates.

rewriting missing links should work now

this introduces stacked locking of the rewrite process which is needed
to keep pages from being rewritten before the missing link info is added
to their metadata.

This works fine for the newly added test case. However in real world
scenarios it might happen that a page is access by someone while the
move operation is in progress. This would still trigger a rewrite,
rendering addition of missing link info too late and create wrong second
rewrites (as seen before this patch in normal operation).

There are multiple ways to fix this:

1) allow absolutely no rewrites during a move (using a file based
locking instead of process based). This would have the disadvantage
of exposing pages with wrong links to end users during a move
2) pass the missing link info over to the ops class so that each moved
page has the info right away and saves it with the other (existing
link) move data in one go. The problem would then be to apply the
missing link move data to all pages that were not affected by any
other link changes. It would need some tracking of already processed
affected pages vs. all affected pages.

Option 2 is most probably the better way to do it. However this is left
for a later iteration for now as the scope of this project is already
slighly out of bounds.

@michitux I'd be happy about any comments, suggestion or - even better -
code here.
