pfSense

Fixes #2979

. Change max value for traffic and packets graphs to 20GigE
. Bump config version to 9.6
. Write a config upgrade function to tune current rrd files to the new
max value

"block" is also a reserved keyword that can't be an alias name, or pf tosses an error.

Merge pull request #656 from swatspyder/master

URL encoding the user/pass for dnsomatic, since it accepts all characters.

Update dyndns.class

To remove a curl_setopt line that is unused for "dnsomatic", and to allow for all characters to be used in the username and password fields.

Fixes #3001, Check the protocol of the webgui to determine if https is being used for custom ports.

Fix whitespace

Fixes to get routes + dns working:

. Simplify code using new parameter of get_staticroutes()
. Check for subnets instead of ip addrs
. Avoid touch filterdns when we are just updating dns

Add extra param, off by default, to make get_staticroutes() return hostnames too

Last element is always empty, be sure we drop it

Permit to use aliases containing hostnames on static routes
