Merge pull request #262 from KurtStam/master

adding distro fix
All verbs are now secured.
Implemented the xp2:not() function for s-ramp queries.
Added two convenience methods on the s-ramp client.
Changed artifact delete to be a logical rather than a hard delete.  The
artifact JCR node is now stripped of its sramp mixin type and moved from
/s-ramp/ to /s-ramp-trash/.  The move isn't strictly necessary but it
was an easy way to make sure getArtifact wouldn't be able to find it.

Refactored the JarToSrampArchive (artifact expansion) code to make it
pluggable (using java serviceloader).  Now additional implementations of
JarToSrampArchive can be contributed (e.g. the switchyard integration
module can contribute its own impl).
