The call stack is pretty loose on is_fqdn() as it is called by
system_routing_configure() which gets called in an uncontrollable
fashion in interface.inc.

This needs to be ported to the python backend table, because
this code requires nmap to be installed...

Instead of injecting dynamic gateways after reading the config, we will
inject them before instead.  This gives us the opportinuity to check
for matches and remove disabled gateways, finally addressing #933 in a
sane way.

created a fix for 914 (openvpn-client-export.inc)

o Allow to delete WAN, LAN is worse :P
o Zap spurious 4th column
o Shorten assign text prompt
o remove margianlly helpful message

This tries to address table overflow problems we have and is
only meant as a base for further discussion.  It gets rid of
table overflow, e.g. in the dashboard on small mobile screens
by setting "table-layout: fixed;" for all tables.  This breaks
the stacked-to-horizontal emulation, so the workaround there
is to switch it off, which requires a proper viewport detection.

While there, fiddle with the logs template, but for these non-
hooked stacked-to-horizontal tables the fix for table-layout
can't be undone, because that would break the original fix in
the first place.

Moral of the story: tables are deprecated.  ;)

LAST TIME THIS WILL BE MOVED LIKE EVER. :P
