Add /MT to MSVC when compiling shared library

When compiling the shared library of DUMA with default /MD, it will raise LNK4006 error. (I forgot the error message... Maybe strcat or something in C runtime library)

I set /MT, and it compiles successfully. But that may raise error when link with an application with /MD.

Notice: Set /MT or /MD to every subproject in the project (such as stacktrace library, see #184)
