Disabling component before 2.3 release

Hi,

Since we are between the last beta and the RC it is time to disable the 
components that are not ready for releases. I suggest we discuss them in this 
thread.

The best solution is to move them to the plugins/stagging directory, because I 
will remove that directory from the release tarball, as well as of the 
branch/2.3.

If there are libraries features that are causing problems, I am not sure how 
to proceed, but we can discuss this on a case by case.
