Function GetMajorVersionFromVersion

src/main.cpp:6373–6385

* Parses major version from version string. * * Version string is expected to be [any text]:X.X[.X[any text]]. * As an example, Luxcore uses /Luxcore:X.X.X/ version string. So, this function will * return 5 for /Luxcore:5.0.0/ or 0 if it couldn't find ":" or "." delimeters, or if no digits are between * those delimeters, or if string verison is empty * @param cleanVersion Luxcore wallet vers

 * @return Major Luxcore major version or 0
