New static network filter option ipaddress=

Browse Source 
The purpose is to block according to the ip address of a network
request. In the current implementation, the filter option can only
be enforced at onHeadersReceived time.

The new filter option cannot be enforced in Chromium-based browsers
since the ip address of network requests is available only at
onResponseStarted time, which is not blocking.

The value assigned to `ipaddress` can either be a plain string which
must match exactly a given ip address, or a regex which will be
matched against the ip address.

The `ipaddress` option can only be enforced when the extension
framework does provide a valid ip address in a onHeadersReceived
listener. For instance, cached resources do not have a valid ip
address and thus can't be a match to `ipaddress` option.

Example:

  *$script,ipaddress=93.184.215.14
