Does not seem to support dynamic dependency JAR loading from public repositories

[xtrntr]

May be related: https://issues.apache.org/jira/browse/ZEPPELIN-169

How to replicate:

z.load("org.zouzias:spark-lucenerdd_2.11:0.3.7")

or any other public JAR i.e. z.load("org.scala-saddle:saddle_2.10:1.3.0")
