Merge pull request #279 from randombit/fix-static-lib-registration

Move the algorithm factory functions to T::create and move object registration to the source file for its base class. These resolve the issues which prevented successful use of a static library that was built with individual object files. Removes the restriction in configure.py which prevented building non-amalgamation static libs.
