Simple check of firewall status
support new appconfig arch
Fix mkdir reported by Jamyn
fix entryurl
update appconfig file

Improved use of localization (and explicitly use Cpanel::Template).

- note rt that make the override moot (should we do apply that now and ditch the override?)
- use makevar() in the template to avoid the need to do what rt describes and to avoid needing a funny method

of note: the text is not marked as translatable so parsers will miss it (this is true w/ out this chnage, with this change, or with the evaltt approache listed at the rt)
