Revision 644034

HBASE-547 UI shows hadoop version, not hbase version
We now show hadoop and hbase versions in master. Also cleaned up how
the jsp is generated moving it into main build.xml done as a pre-compile
step.
D src/java/org/apache/hadoop/hbase/generated
  Removed this directory. No longer check in jsps. Generate them every time.
M src/webapps/regionserver/regionserver.jsp
  Use the hbase VersionInfo so we get hbase version, not hadoop's.
M src/webapps/master/master.jsp
  Output hadoop and hbase versions.
D build-webapps.xml
  Remove. Integrated into main build.xml. Reason we were doing this
  distinct  C --CLASSPATH issues when compiling in hadoop context  --
  no longer prevail.
M build.xml
  (jspc): Added target and made it a prereq of compile.
