- The default 'postinst' from 'luci.mk' is sufficient for what we need, also updated the 'uci-default' to a standard version
- Hack about 'header_login' is replaced with adding 'out_header_login' directly from the sysauth template
- Also added specialized 'out_footer_login' and 'footer_login' for symmetric reasons
- Synced 'out_header_login.htm' with current LuCI 'header.htm'
