[TYPO3-core] RFC: fixing bugs 1642 and 4886: menu does not reload when installing an extension with a new BE module

[Ingo Renner]

Hi all,

This is SVN patch request.

Branch: trunk

Problem:
When installing or uninstalling an extension which contains BE  
modules the ne modules don't show up in the menu


Solution:
Reload the menu frame.

Reloading the menu frame isn't enough though. The available modules  
are defined in goToModule() - a javascript function generated in  
alt_main.php. Thus it is not updated and the newly appeared module  
will not work unless the whole BE is reloaded.

To challenge that the generation of the goToModule function had be  
moved to the respective menu frame (left / top select / top icons).  
This ensures that the function including the module definitions is  
reloaded, too and the newly appeared module will work when clicked.

To keep references to the old top.goToModule() function working it is  
turned into a wrapper for the moved JS function and will simply  
forward the call to the correct frame.
