fixed compilation on windows
build libCEC and cec-client against toolset v100 (VS2010). lots of 3rd party libs/programs and their installers only install the previous C++ redist, which will make libCEC fail to load when not manually installing the redist. we can include the correct redist in libCEC's installer, but that will still lead to problems when users just install XBMC from http://xbmc.org/ which doesn't include the v110 version of the redist. users will get a crash with the CEC adapter connected, not telling them how to fix the issue (thanks MS)
