restructure Functions Before and After panel closing

Add two new Functions: BeforPanelClose and AfterPanelClose. This gives a
better overview to which part of the CodeBrowser the associated
Functions belong:

* The hook as to be unbound from the panel.
* Panel Variables and Waves (only killed if panel was killed prior)
* Package Pref Variables (killed after Syncing PackagePrefs at Program
Quit.
* Storage Variables and Waves (can be killed at any time after unbinding
the hook
