Modifier to become Action-Option

[<duncan@sfractal.com>]

An issue was discussed and resolved at the last Language Subcommittee
that the Modifier field move under Action and be action-option. Since
this is a relatively major change, it is being communicated to the the
TC mailing list.

A wiki page was created for this issue at
https://wiki.oasis-open.org/openc2/ModifierOnAction but the content will
be repeated here:

"The language specification previously defined the openc2 command as
having 4 components: 

+ action (mandatory) 
+ target (mandatory) 
+ actuator (optional) 
+ modifier (optional) 

At the 29-Aug-2017 Language Subcommittee meeting, Allan Thomson of
Looking Glass raised the issue of whether 'modifier' belonged as a peer
to action or as part of action. Targets have target-specifiers and
target-options and the issue was whether modifier was really an
action-option. Bret Jordan of Symantec supported this view with the
argument it would be easier for vendors to adopt openc2 since it would
be easier to understand. The issue was raised by DuncanSparrell
(speaking as sFractal Consulting and software developer of ocas, not as
co-chair) that this was a significant change to something that has been
stable for 2 years and that any software already written would have to
be changed. It was observed that the purpose of the SC was to get input
and that changes were to be expected. 
The argument that it would increase vendor adoption was significant as
everyone agreed that increased vendor adoption would be beneficial.
Consensus was reached that modifier would move to action-option. The
changes to the Language Specification that result from this will be
reviewed at the next meeting."
