Asynchronously save a content filter from a set source rule.
Asynchronously save a content filter from a source rule set in the WebKit content extesions JSON format.
The identifier can be used afterwards to refer to the filter when using
remove and
load. When the identifier has been used in the past, the
new filter source will replace the one saved beforehand for the same identifier.
When the operation is finished, callback will be invoked, which then can use save.end to obtain
the resulting filter.
