Update thrift README and HBase.thrift to use thrift 20080411

Hey,
When using thrift as per the README.txt in
$HBASE_HOME/src/examples/thrift is outdated and uses deprecated
arguments for thrift.  The command should be

$thrift --gen cpp --gen java -gen rb \
    ../../../src/java/org/apache/hadoop/hbase/thrift/Hbase.thrift

Also, the Hbase.thrift file is a little outdated.  It uses namespaces now.

java_package org.apache.hadoop.hbase.thrift.generated
cpp_namespace apache.hadoop.hbase.thrift
ruby_namespace Apache.Hadoop.Hbase.Thrift

Should be

namespace java org.apache.hadoop.hbase.thrift.generated
namespace cpp  apache.hadoop.hbase.thrift
namespace rb Apache.Hadoop.Hbase.Thrift

I have attached both patch files.

Thanks,
Michael
