log4sh 1.4.2

log4sh project is a logging framework for shell scripts that works similar to the other wonderful logging products available from the Apache Software Foundataion (eg. log4perl, log4j).
Although not as powerful as the others, it can make the task of adding advanced logging to shell scripts easier, and has much more power than just using simple "echo" commands throughout.
In addition, it can be configured from a properties file so that scripts in a production environment do not need to be altered to change the amount of logging they produce.
Enhancements:
- updated shUnit to shUnit2-2.1.1pre
- added support for the fully qualified class name when using a log4j
- configuration file.
- fixed some variable use standardization (i.e. wrapping in {} chars)
- fixed bug in log4sh_readProperties() -- it was not calling log4sh_doConfigure()
- like it was supposed to.
- added some error checking to log4sh_doConfigure and _log4sh_propAppender() so
- that a useful unit test could be written to verify propert log4j compatibility.
- added testPropertyConfig and testLog4jCompatibility unit tests.
- backported the testSyslogAppender unit test from 1.5.0
- fixed error message in log4sh_setAlternative() when the alternative commmand
- not found. it now makes more sense.
