ignore *.jar in project root
ignore *.jar in project root

Added the maven-dependency-plugin to POM files for OSGi bundles (copies
dependencies to project roots).  Needed to add a line to the list of
ignores so that JAR files don't show up as new untracked files.
added maven-dependency and maven-clean plugins

Added these plugins to facilitate being able to run Protege with an OSGi
Framework launcher in Eclipse, when using PDE and m2e.  Also added the
org.eclipse.m2e plug-in to eliminate an m2e error in Eclipse.
