Only show enable all / disable all buttons for all add-ons when at least one add-on is installed. When no add-on ist installed, don't show any buttons or checkboxes. Added is_modpack flag to ModSpec to distinguish empty modpacks from normal mods and check this flag in mod selection gui so that empty modpacks are not treated like mods that can be enabled or disabled.
