Transparent Cutout Soft Edge Unlit Texture Blend

Sahilramani:

==Description==
[[File:Blend0.png|thumb|_Blend=0]]
[[File:Blend5.png|thumb|_Blend=0.5]]
[[File:Blend1.png|thumb|_Blend=1]]
Modified Transparent/Cutout/SoftEdgeUnlit shader to include blending between two different textures given a blend factor.

==Usage==
The "_Cutoff" variable specifies the base alpha cutoff, just as it does in the original shader.

The "_Blend" variable specifies the blend factor, while "_Texture1" and "_Texture2" specify the two textures to be blended.

Note that when _Blend=0, _Texture1 will be selected and when _Blend=1, _Texture2 will be selected.
