SBSMS library/effect changes. Apparently resolves bug #170. Incorporated optimizations with minor quality changes. Returned optimization flags to build (introduced in a patch). The audacity SBSMS branch is now a trimmed down version without associated programs. Includes (untested) changes to the windows .vcproj.
