Title: Windows multi-cpu compile

This adds the `/MP` option when calling `cl.exe` in the MSVC toolchain. This results in a nice reduction of compile time. I tried this by running clean and slightly-dirty builds, using msbuild with options that closely mimic the behavior with Visual Studio but with more information.

You can see the full logs [here](https://gist.github.com/2144073). "Change" builds were generated by adding this line to `tests-clar/commit/commit.c`:

void test_commit_commit__new_test(void) {}

The command for building was this:

msbuild .\libgit2.sln /m /detailedsummary
