[Greasemonkey] GM_setValue, getValue and default values for preferences

[Ori Avtalion]

Attached is a patch that removes script-created preferences when 
uninstalling a script.

The "scriptvals.script-namespace.script-name" string now appears twice 
in the codebase: miscapis.js, manage.xul.
Perhaps it should be saved as "script.prefStartPoint".


In case you have left-over greasemonkey preferences from previously 
uninstalled scripts, just reset the preference in about:config.
They will be automatically removed when firefox is restarted.

This behaviour has nothing to do with greasemonkey. I think firefox does 
that for all user-created scripts.

Next patch coming soon.
