updated to compile with current g++

Added __dso_handle to the body of the main cc file for each of the
shared libraries (why is this broken up?)

Also cleaned of some minor errors.
What did we change? just a bit of smarter debug info..
Ok merged a fix

Merge branch 'master' of github.com:nachiket/ScoreRuntime
