Improve page tree performance
To detect a double click to edit a page title the page tree
literally waits 400ms before it loads the content area.
besides that the loading mask suggests a not loaded page, while
most of the content is already there.
The latter should just be dropped. It was iirc only included to
not break pure extjs modules while not completely initialized.
For the first, we need an alternative to easily edit page titles inline
[TASK] Massive performance improvement for page tree
This patch improves the performance by removing delays.
A single click in the tree loads the page now significantly faster, however,
the page is now loaded also with a doubleclick.
With a tree implementation without ExtJS we can change this behavior again.
