removed mapper, replaced by instantiator
removed methods from CoreUtil that are no longer used, added isBuiltin
instantiator now maintains list of built-in entities
corrected NPE when using generic types with no size (int<>)
updated entity info to create resource
This is because the instantiator will run only once each time per build
(validation + code generation cycle), and the resource set is new for
each build.
added "execute" method to instantiator, improved code
removed setEntity, inlined into execute
entity mapper now sets entity name differently for builtin entities
corrected a couple of syntax errors in VHDL, replaced Studio by ngDesign
corrected serialize method to use correct URI in ModuleCompilerImpl
