Improvements to *JavaHome types

Previously the ImmutableJavaHome.do_with() method used the $PWD
qualified version of JAVA_HOME.  This caused problem during some
executions, so both of the *JavaHome types have been changed such that
the fully qualified path is used in the do_with() method.

Logger support for non-block message

Previously, only messages passed to the logger via a block would be
printed.  Due to the wonky logger API, messages and prognames are
interchangeable and this was not taken into account in the
implementation.  Since the progname is fixed at logger creation time,
we were discarding any other value that might be provided (which at
times could be the actual message).  The new implementation uses the
input message or input progname, whichever is not nil, as the message.

Find JDBC driver JARs in subdirectories

Previously, the JDBC driver frameworks only looked into the root of an
application to find the JDBC driver JARs that would cause them to
avoid.  This was an error as many times those JAR files would be in a
nested subdirectory (e.g. WEB-INF/lib).  This change fixes this bug
and causes the JDBC driver JARs to be detected anywhere in the
application's filesystem.
