-- Split the Mac-specific parts of the GCC toolchain into their own toolchain derived from toolchain_gcc.
-- Added an option to specify the standard library to be used with the GCC toolchains.
-- Added a switch to enable hidden visbility with builds under the GCC toolchains.
-- Added LoadableModule as a new output type. When building through any Apple-based toolchain, LoadableModule will generate a ".bundle" file. All other toolchains will treat it exactly the same as SharedLibrary.
-- Disabled SlickEdit project generation since it's been broken for a while and shouldn't be used until it's fixed.
-- Add an OSX unit test, HelloLibraries, to test building and linking/loading different types of libraries into an application. This might become a generic unit test later on, though the LoadableModule will probably need to be excluded from non-Apple builds.
-- Added more .gitignore's for .DS_Store files.
-- Removed the sys.path construction to include the local copy of csbuild.
