Servus: use interface param in avahi impl
Added imagehlp to the list of dependencies for WIN32 builds
Changed the header name "DbgHelp.h" to lowercase letters. This should make no difference for systems with case insensitive file names such as Windows, but enables compiling on a host with case sensitive file names (e.g. Linux).
Removed SAL (source-code annotation language) annotations, because they are specific to MSVC.
Replaced "unsigned __int64" with the more portable type "unsigned long long".
Added a check for MinGW before including the GCC specific header <parallel/algorithm>.
Replaced checks agains the _MSC_VER macro with the more general _WIN32 to support othe compilers on Windows.
MSVC specific code for structured exception handling will now only be included when MSVC and not any other compiler is used on Windows.
Exported constructor and destructor in lunchbox::Referenced to allow for a build with MinGW.
Changed include path to lower-case to support compilation on case-sensitive Windows targets.
