add videoAVT visual C++ project files
include depends on MSCV version

starting with Visual 2010, we need both `winsock2.sh` and `WS2tcpip.h` instead of `winsock.h`
force callback method cast

MSVC is not smart enough to cast it itself
add videoAVT to Visual 2010 solution
add Pylon Visual project files
Pylon::CBaslerGigEStreamGrabber seems to have been replaced by Pylon::CPylonGigEStreamGrabber

I have to change that to compile with SDK version starting at 2.3.0 (the older still available on Basler website)
bool method should return a bool
force cast of Pylon::EPixelType

maybe a flag to MSCV could avoid this
add some flags and lib for compiling
seems that API have changed

those lines lead to : error C2065 : undefined identifier
