qtgui: accounted for MSVC having _finite() instead of std::isfinite()
cmake: fix FindUHD.cmake to work with UHDConfig*.cmake, not FindUHD.cmake, since that's what UHD will be installing.  UHDConfig* is a more robust way to find packages, and works with default CMake internal paths.
blocks: Fixed some broken license headers
uhd: Fixed minor issue with kwargs in amsg_source
qtgui: Added a 'vector sink'.

This is a sink similar to the freq sink, which takes vectors as input
and plots them as-is.
