-Added parallel link support. Once the compiler starts freeing up threads, they'll be re-allocated to the linker. Sadly, this option isn't possible on Windows due to file locking issues
-Fixed an issue where incremental builds of a project using the msvc toolchain with a precompiled header would fail to link the precompiled object in if the object did not need to be recompiled.
--To support this fix, all build events (preCompileStep, postCompileStep, etc) are now called on the toolchain before being called on the project.
