On Linux and macOS, using Clang to compile OpenStarbound produces about 400 MB worth of warnings during the build, making the compiler output unreadable and slowing the build down considerably. 99% of the warnings were unqualified uses of std::move and std::forward, which are now all properly qualified. Fixed a few other minor warnings about non-virtual destructors and some uses of std::move preventing copy elision on temporary objects. Most remaining warnings are now unused parameters.
