#44 support direct instrumentation of J2EE archive files

[Vlad Roubtsov]

As an end user convenience, InstrProcessor should be
able to handle .war, .ear, etc files (the fullcopy mode
probably needs a new <out dir>/j2ee sub-location or
something to that effect).

This does, however, raise the issue of being able to
specify class/lib inclusions/exclusions inside such
archives. This requires filter syntax to be extended and
most likely needs to be done consistently with this FR:
http://sourceforge.net/tracker/index.php?
func=detail&aid=979819&group_id=108932&atid=651900

Note also that allowing J2EE archive files in instrpath
strings deviates somewhat from the traditional content
model for path strings.
