Improve Footer links

[PatrickRQ]

Hi IPS,

Please consider ability of extending links in footer by guidelines, cookies, terms of use, same way you do with privacy, etc

Examples:

  	<li><a href='{url="app=core&module=system&controller=cookies" seoTemplate="cookies"}'>{lang="Cookies"}</a></li>
  	<li><a href='{url="app=core&module=system&controller=terms" seoTemplate="terms"}'>{lang="terms_of_use"}</a></li>
	{{if \IPS\Settings::i()->gl_type != 'none'}}
  		<li><a href='{{if \IPS\Settings::i()->gl_type == "internal"}}{url="app=core&module=system&controller=guidelines" seoTemplate="guidelines"}{{else}}{setting="gl_link"}{{endif}}'>{lang="guidelines"}</a></li>
	{{endif}}
