Attempt to fix Travis-CI configuration again
Attempt to fix Travis-CI configuration again

Remove the environmental variables causing build errors completely.
Rename the Docker build runtime name to clarify the run is executing
the Travis-CI build. Alter the declared language to be Java to more
clearly reflect that the build is in fact a Java/Maven project, despite
the fact that Docker is used heavily during the Travis-CI build process.
