[MASSEMBLY-617] Add a suffix element in fileSet (same as destName in file)

**[thomas collignon](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=tcollignon)** opened **[MASSEMBLY-617](https://issues.apache.org/jira/browse/MASSEMBLY-617?redirect=false)** and commented

The purpose of the wish is to add a "fileSuffix" attribute in fileSet descriptor. This will add a suffix in all files in the fileSet.
Exemple :
test.xml with TOTO suffix => testTOTO.xml (in the zip)

This is the same as destName in file descriptor but this is for all the files in the fileSet.

I think this need to modify this jars too :
- plexus-io
- plexus-archiver

I have already made all of this modification and if you want the source code, I can give you.

Regards

Start by reviewing fileSet descriptor handling in maven-assembly-plugin and the referenced plexus-io and plexus-archiver components. Compare GitHub Pull Requests #4 and #5, then verify that a fileSet suffix produces names such as testTOTO.xml for every included file.
