Closes#403.
This change is actually two-fold:
a) bif's now accept module XYZ; statements and module::ID for
function, const, event, enum, etc. declartation
b) Added C++-namespaces to variables, functions, etc. that are declared
in bif but accessed from C++
This required some (lightweight) re-factoring of the C++ codes.
Note, event's don't have their own C++ namespace yet, since this
would require a rather huge re-factoring.
Compiles and passes test suite.
New namespace feature not tested yet.
Documentation to follow.
