Rename OpenJDK and Oracle JREs

Previously, the Oracle JRE's component name was simply 'Oracle'.  This
is ambiguous (it might indicate a database), and thus needed to be
changed.  The choice for the new name was 'OracleJRE'.  To stay in-
line with it's naming scheme, the OpenJDK JRE component was renamed to
'OpenJdkJRE'.
