Clean up name delegation in the plugin.  A few rules:

* Each configuration should have its own `name` and `normalizedName` instance
* Debian/Rpm delegate to Linux which delegates to project name.
* Universal has its own name, which is used for generating BASH/BAT files
* Separate key for the package filename now
* Windows has its own name/normalized name which delegates to raw.

Support EXPOSE [port] ... for Docker

Docker allows the ability to share ports between containers, if the ports
are listed in the configuration for the Docker image. This commit adds a
dockerExposedPorts setting which adds the appropriate line.

Support EXPOSE [port] ... for Docker
Allow name in Docker to be modified.
Support Docker volumes.

Docker has a feature where it can import or export "volumes", or subtrees of
the filesystem which can be shared in different ways between Docker containers,
or between a container and the host machine.

This adds the command to the Dockerfile which sets up the knowledge inside
Docker. Also, if a directory is created which does not exist, it will be owned
by root. This would be unfortunate if, for example, the exported directory
was the logs/ directory for Play. So the directories are created beforehand.
