[Typo3-dev] New hook suggestion.

[Stig Nørgaard Færch]

Hi guys

Tell me if it's bad manner to post this here. Hope not.
http://bugs.typo3.org/view.php?id=1481

Currently, if you want to put something in the topmenu frame in the 
backend, you will have to do this through Xclassing. The problem is that 
many developers have installed the 'extdeveval'-extension which makes 
use of Xclassing to display links in the topmenu frame. That means that 
other extensions can not access this space.
In this patch I have implemented a hook in alt_topmenu_dummy.php which 
makes i possible for multiple extensions to add content to the topmenu.
It's possible to set a placement priority(1-9) through the variable 
'priority' of the class which the hook connects to.
This hook is needed if you want to use both 'Roles'-extension and 
'extdeveval'-extension.

On bugs.typo3.org you can also see an example-gif from the backend.

Best Regards
Stig N. Færch
