- Added all_modules_ to hold pointers to ALL allocated modules.

Browse Source 
- Add a private set_uninitialized() method for resetting the
  initialized_ flag and I also clear the contents of bmodules_ and
  cmodule_. initialize() will repopulate them.
- Fixing a memory leak in remove() - previously, when cmodule_ was
  being removed, it was not deallocated.
- Attempted to simplify the DecimaterT<Mesh>::initialize method.
- Added a "FIXME" comment critical of special treatment of quadric module.
- Replaced -1 with proper ILLEGAL_COLLAPSE enum constant in
  collapse_priority.
