Add 'scala-jar' to the list of jar artifacts.

The CustomPomParser has a hard-coded list of 'blessed' Maven POM packaging types
that are actually packaged as jar files, but Ivy incorrectly maps the file extension.
This patch allows artifacts published with the 'scala-jar' packaging to be properly
resolved and used in an SBT project.
Add a unit test for the 'scala-jar' mapping.
Triggered Execution should be aware of rename or move file
Make jar artifact a 0-byte file.
