Adding a new hook system for firewall nat edit and firewall rules edit page.

Basically if the directory exists it will suck in the files to extend these pags.

/usr/local/pkg/firewall_nat/input_validation
/usr/local/pkg/firewall_nat/pre_write_config
/usr/local/pkg/firewall_nat/htmlphpearly
/usr/local/pkg/firewall_nat/htmlphplate

/usr/local/pkg/firewall_rules/input_validation
/usr/local/pkg/firewall_rules/pre_write_config
/usr/local/pkg/firewall_rules/htmlphpearly
/usr/local/pkg/firewall_rules/htmlphplate
