omero load --glob

[manics]

Closes #120

For example, omero load --glob /opt/omero/server/config/*.omero will sort files /opt/omero/server/config/*.omero before loading them

LGTM. Merging. The only feature I can imagine is that the commands that are being loaded could also show up under self.ctx.dbg:

(omero-virtualenv) bash-4.2$ head t/0*
==> t/01.omero <==
version

==> t/02.omero <==
admin ice server pid Blitz-0

==> t/03.omero <==
config get
(omero-virtualenv) bash-4.2$ bin/omero -d1 load --glob t/*.omero
