Add reload and force reload buttons for apache2, samba, and other similar plugins

Some configuration edits of programs like apache2 or samba can be updated using the reload parameter instead of restarting the server.

service apache2 reload
service apache2 force-reload

I use it (and I think I'm not the only one..) most ofthen than restarting the server, wich is slower.

This is why I think you could add reload buttons for those plugins that have the functionality.
