[TYPO3-core] RFC #4885: AJAX pagetree update could be used when a new page is created

[Benjamin Mack]

Hey guys,

this is a SVN patch request.

Branches: trunk only

BT reference: http://bugs.typo3.org/view.php?id=4885

Problem:
When a new page is created, the page tree is triggered to be refreshed 
by a javascript call: top.content.nav_frame.refresh_nav(). This 
behaviour could also be achieved by the new AJAX pagetree. To speed up 
reloading, only the updated branch of the tree has to be loaded.

Solution:
I first made the BEfunc getSetUpdateSignal so it could take additional 
parameters (here: the branch of the tree). Also, I didn't like the 
coding design that one function does both setting the update signal and 
retreiving the JS code for that. So I split that while keeping backwards 
compatibility.
Then I needed to fix the AJAX-call through using a absolute path for the 
ajax.php in the. I also added the new function "refreshBranch" which 
takes a list of pages to refresh. It takes the same AJAX call as with 
the expand / collapse code.
Additionally I implemented the first improvement when editing page 
properties. Try it out: Edit a page record and e.g. change the title. It 
will refresh only the branch.
