Build packages automatically when installing
Merge branch 'master' into issue186
Simpler package installation from manifest.xml

Use manifest.xml for default addon packages on coreBOS installation
instead of creating zips and installing them. Packages are defined in
install/installAddons.php.

I've changed vtlib_toggleModuleAccess so it doesn't fire events when
installing, this avoids errors.
Remove unneeded script
