Add a new command that lets you wait for an attribute to appear in
a value. Using this you can do things like wait for a managed entry
to be created, adding a new objectclass to the parent entry.

This is controlled by a new booleon option, wait_for_attr, defaulting
to False.

We collected the failures but didn't report it back. This changes the
API of most delete commands so rather than returning a boolean it returns
a dict with the only current key as failed.

This also adds a new parameter flag, suppress_empty. This will try to
not print values that are empty if included. This makes the output of
the delete commands a bit prettier.

The changes include:
 * Change license blobs in source files to mention GPLv3+ not GPLv2 only
 * Add GPLv3+ license text
 * Package COPYING not LICENSE as the license blobs (even the old ones)
   mention COPYING specifically, it is also more common, I think

This will allow others to provision on behalf of the host.

This also requires a resolvable hostname on services as well. I want
people to think long and hard about adding things that aren't resolvable.

The cert plugin can automatically create services on the user's behalf when
issuing a cert. It will always set the force flag to True.

We use a lot of made-up host names in the test system, all of which require
the force flag now.

ticket #25

The attributes displayed is now dependant upon their definition in
a Param. This enhances that, giving some level of control over how
the result is displayed to the user.

This also fixes displaying group membership, including failures of
adding/removing entries.

All tests pass now though there is still one problem. We need to
return the dn as well. Once that is fixed we just need to comment
out all the dn entries in the tests and they should once again
pass.
