Lots of minor changes to support building on Visual Studio. A few MSVC-specific #ifdefs to eliminate things Visual Studio doesn't like. This version now compiles on Windows (provided liblo, Juce and pthread are present) but the TouchKeys device support is not yet enabled. Also, the code now needs to be re-checked on Mac and Linux.
