Harmonize with current dspace-pom so it will build.
Add a .gitignore
License header updates also needed to build
Replace J.U.L. logging with log4j.
LocalHostRestrictionFilter creates a logger but never uses it.  If we
remove it, we can get rid of the Commons Logging dependency.

Also add some direct dependencies drawn in by our modified FacetComponent.
Add code to configure log4j from a file that can be specified by a context parameter.
Display the source of the configuration to the context's log.
Provide a filterable default path to the logging configuration
Replace 'dspace-pom', now deprecated
Also add Travis configuration
