Partial reimplementation of compiler and TypeTable

Every type symbol and its possible polymorphic variables are now
parsed up front and put in the SymbolTable, doing away with the
complicated and error-prone NamespacedIdentifier. Still pending
changes to parts of the compiler and the runtime, so not working
at the moment.
