Set default beam intensity to 1 instead of 0

A beam intensity of zero is handled by BornAgain as a special case, disabling any form of normalization of the pixel intensity (alpha factor, intensity, pixel solid angle). We should probably keep this for some special cases, but definitely not have this as the default.
