Modify package trigger handling. Now the triggers update-fixperms and update-locale are only called during package installation. Do not execute them during the package deinstallation will save CPU resources and time. The plugin translation are useless now, but do not harm anyone, thus we can simply ignore them and improve plugin deinstallation speed.
