Clarify install instructions

[danvk]

The Tools page says:

build a jar then run:
java -cp itunes.jar org.kafsemo.titl.tools.command

I've tried:

git clone https://github.com/josephw/titl.git
cd titl
mvn package
java -cp titl-rdf/target/titl-rdf-0.3-SNAPSHOT.jar org.kafsemo.titl.rdf.LibraryAsRdf
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/openrdf/model/URI

Those instructions will only work for titl-core, as title-rdf has extra dependencies. Use exec-maven-plugin or add the libs to the classpath yourself.

Thanks, I'll give that a try.

FWIW, I also get an error from the other JAR:
