HADOOP-1375 a simple parser for hbase

M src/contrib/hbase/NOTICE.txt
    Add notice of udanax contributions.
Msrc/contrib/hbase/conf/hbase-default.xml
    (hbaseshell.jline.bell.enabled): Added.
M src/contrib/hbase/CHANGES.txt
    (hadoop-1375) Added.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/package.html
    Add note on how to start up hbase shell
M src/contrib/hbase/bin/hbase
    Add 'shell'.  Remove 'client' (shell does what it used do and more).
    Removed all reader and logreader until better developed.  Starting
    up a reader or logreader on a running hbase system could do damage).
M src/contrib/hbase/build.xml
    Add a javacc target to generate content of shell/generated subpackage.
