* extract NamespaceFactory from TypeHierarchyResolver
* implement NamespaceFactory.createNamespaceDescriptorPathIfNeeded(FqName)
* FqName .path() and .pathSegments() utilities

added hook for caching preparedStatements along with simplifying the logic of using PreparedStatements as we make the statement up front, then bind directly. Also support most of the common data types (though need more null support)

* required parameters have @NotNull annotation generated
* parameters are required by default

moved the stdlib tests into the same directory as the stdlib, so it works a bit better with maven support in IDEA

removed the old experiments for templating; so we now just create a StringTemplate object that can be converted to html or used with JDBC queries/statements etc

* ModuleDescrpiptor now lives in context
* ns parent is module descriptor iff ns is root ns
* minor test enhancements

#KT-1565 add a StringTemplate class which takes a Tuple - also add a Tuple so we can easily generically process all the items in a tuple
