Fix 2019.1 compatibility issue

[SetoKaiba]

Referred from vrm-c/UniVRM#237

After a deeper dig, I found out the problem is caused by the line below.
UsePass "Standard/SHADOWCASTER"
The problem is introduced by the new modification on Standard.shader. It uses shader_feature_local instead of shader_feature.
The shader_feature_local will just make the keywords for multi_compile and shader_feature not working anymore.
And also, the problem can't be reverted. Once you compiled the shader with shader_feature_local. Even you remove the lines.
The keyword will still not work.

The temp workaround is to delete the shader. And use the code below for a temp fix. I'll still wait for the replies from official and give more updates here.

			Pass {
				Name "ShadowCaster"
				Tags { "LightMode" = "ShadowCaster" }

				ZWrite On ZTest LEqual

				CGPROGRAM
				#pragma target 3.0

				// -------------------------------------


				#pragma shader_feature _ _ALPHATEST_ON _ALPHABLEND_ON _ALPHAPREMULTIPLY_ON
				#pragma shader_feature _METALLICGLOSSMAP
				#pragma shader_feature _SMOOTHNESS_TEXTURE_ALBEDO_CHANNEL_A
				#pragma shader_feature _PARALLAXMAP
				#pragma multi_compile_shadowcaster
				#pragma multi_compile_instancing
				// Uncomment the following line to enable dithering LOD crossfade. Note: there are more in the file to uncomment for other passes.
				//#pragma multi_compile _ LOD_FADE_CROSSFADE

				#pragma vertex vertShadowCaster
				#pragma fragment fragShadowCaster

				#include "UnityStandardShadow.cginc"

				ENDCG
			}

Thank you for your contribution.

I try to solve this problem with your temp fix and check Unity's version compatibility.

Sorry for the spam and I can see this issue is closed.
But a Unity related problem led me here and thanks for the info.
Any news from the unity official?

EDIT:
Is there any other workaround instead of deleting the shader?
I tried delete the Library/ShaderCache folder but I didn't work. I'll try deleting the whole Library folder now.
