Java Meterpreter process.execute and arguments

[todb-r7]

Issue rapid7/meterpreter#98 is really a Java thing, but was opened over there so the links from Redmine would work as expected.

What actually should happen is some more sane and thoughtful naming of this repo, or have everything be a subproject of rapid7/meterpreter, or something. I know we talked about this, but that's way beyond the scope of this bug.
