war plugin doesn't support lists of includes/excludes

The war plugin uses

<classes dir="${maven.build.dest}">
<include name="${maven.war.classes.includes}" />
<exclude name="${maven.war.classes.excludes}" />
</classes>

to build up the list of files to include in the war file.
This prevents the specification of a lists files to include and exclude, eg:

maven.war.classes.includes=org/foo/*,org/bar/*
maven.war.classes.excludes=org/foo/ter/*,org/bar/fly/*

The fix is to replace the nested <include> and <excludes> as follows:

<classes dir="${maven.build.dest}"
includes="${maven.war.classes.includes}"
excludes="${maven.war.classes.excludes}" />

Patch to follow.
