Debug logging

[stephenatwork]

I just installed the latest binaries. Compiling an individual file via the context menu works (after working around #13). However, choosing Clang->Rebuild Active Project gives

ClangVSx 0.5 | LLVM/Clang C++ Compiler Bridge | www.ishani.org

Exception During Build : 
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

It would be helpful to have some logging to dig into the problem. Or if it's already there, some mention of it in the docs.

Do you have a repro project you could send though?

Unfortunately, it's a closed source project. However, it seems to be before any compilation has even begun so perhaps the error is triggered by something in the vcproj?
