Propagate token namespaces to treenode.

Welcome to Hoa\Compiler\Llk\TreeNode::getNamespace() method.
Dump namespace if different of 'default'.
Propagation of namespaces has been moved.

Namespaces cannot be properly resolved during the analyzing of the
grammar. A token namespace is really known during the lexing of the
parsed data (or during the sampling of a grammar).
Propagate token namespace in the sampler.
