All 'a.b.ALL' as wildcard config settings

In order to not require setting all properties
under a particular dotted name (e.g. "omero.pixels"),
'ALL' can be appended to the base name in order to
allow all the below (e.g. "omero.pixels.ALL" would
allow "omero.pixels.max_sizeX" and "omero.pixels.max_sizeY".
Working docker processor

Along with the 'omero-process' docker image, this
change will allow launching scripts in a docker container.
What's required at this stage is setting omero.process.python
to omero.processor.DockerProcessI

Host name lookup from within the container is also not optimal.
Provide method for specifying ProcessorI class

Now, by setting impl='' on the Processor instance
in etc/grid/default.xml, a different Processor
implementation can be chosen. This should allow
choosing a Docker-based implementation which accepts
all Python scripts.
Clean web template
Remove early exit from willAccept

This return fails to invoke the callback leaving
the client to receive "0 responses" when there's
possibly a clear message on the clients.
Create DockerProcessorI to accept all python scripts

This servant implementation accepts all Python scripts,
even those uploaded by non-admin users, and executes
them within a Docker container.

To enable, uncomment the Processor in default.xml.
