Retrieve a partial package.xml 1.0 representation of dependencies

a very limited representation of dependencies is returned by this method.
The <exclude> tag for excluding certain versions of a dependency is
completely ignored.  In addition, dependency groups are ignored, with the
assumption that all dependencies in dependency groups are also listed in
the optional group that work with all dependency groups
@param boolean return package.xml 2.0 <dependencies> tag
@return array|false
