Supress errors when opening custom DHCP6 config file and check if content was successfully retrieved.
Prevents PHP from throwing error in case file does not exist.

A mix of literal tabs, spaces and \t is used in dhcp6c config file code. Convert evertyhing to use \t.

DHCP6 config file override, advanced and basic settings override each other so put them in single
if/else statement rather than always generating all three setting types.

Add option for wireless standard "auto", to omit "mode" entirely from ifconfig. This shouldn't be necessary, but specifying mode has proven to trigger driver problems that don't exist if it's left unspecified (such as FreeBSD PR 198680). Chosing "auto" fixes ath(4) BSS mode issues otherwise preventing it from connecting.
