[g4star] Expose partcile stack for the geant4 application.

[g4star] Update stacker and agml extension classes to enable multi engine tracking and user defined hits in the geant4 application.  Few additional fixes and cleanups in the code.

[g4star] Import the StGeant4Maker into the repository.  Builds under root 6.24 (with some additional compilation flags).

[g4star] Defer mysql load until StBFChain can do it.

[g4star] Add geant4vmc, geant4mk and fastjet chain options.  Load libfastjet with stargen package b/c one or more filters depends on it.  (Should consider splitting filters into sep chain opt).

[g4star] Cleanup commented out includes.

[g4star] Reduce compile time warnings...

[g4star] ... more reduction of compiler warnings

... and even more reduction of compiler warnings...

[g4star] And modify cons to pickup the include paths to geant4 and geant4 vmc libraries
