Hbase Version CLI enhancement

Hbase Version CLI enhancements:

1) include source code checksum.
2) change "Subversion" to "Source code repository"

Existing implementation:

hadoop@localhost p4_wspaces]$ hbase version
2014-09-01 03:29:40,773 INFO [main] util.VersionInfo: HBase 0.98.1-hadoop2
2014-09-01 03:29:40,773 INFO [main] util.VersionInfo: Subversion <...>
2014-09-01 03:29:40,773 INFO [main] util.VersionInfo: Compiled by <...>

Expected implematation:

hadoop@localhost p4_wspaces]$ hbase version
2014-09-01 03:29:40,773 INFO [main] util.VersionInfo: HBase 0.98.1-hadoop2
2014-09-01 03:29:40,773 INFO [main] util.VersionInfo: Source code repository <...> <<< change "Subversion" to "Source code repository"
