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.
Helps a little with the lag from recipes when having crafting interfaces open, but it's still noticeable.
Also micro-optimized Root maintenance by unlocking the Root mutexes for their respective shared_ptrs earlier once we have our own shared_ptr.
