Title: Updated PDI Extension Point Scripting to 1.1

Added script points for the following:

Kettle Lifecycle Plugins (use the following as prefixes for your script file names):
environmentInit
environmentShutdown

Lifecycle Plugins (use the following as prefixes for your script file names):
onStart
onExit

I added an onStart.groovy example to the package. When running Spoon, it will now print "Got Lifecycle onStart event" to standard out when the onStart event is received.
