Update the deprecation note, add to msfconsole

This will cause msfconsole to throw a warning as well as msfupdate.

The deadline for action is also set at the end of February.
Lack of action moved the deadline to Mar15

Because this change was delayed in getting
reviewed and landed, moved the SVN deadline
out two weeks.
