Fix texture and boolean property types in subgraphs

com.unity.shadergraph/CHANGELOG.md

 - Your system locale can no longer cause incorrect commands due to full stops being converted to commas.
 - Deserialization of subgraphs now works correctly.
 - Sub graphs are now suffixed with (sub), so you can tell them apart from other nodes.
+- Boolean and Texture type properties now function correctly in sub-graphs.
 - The preview of a node does not obstruct the selection outliner anymore.
 - The Dielectric Specular node no longer resets its control values.
 - HD PBR subshader no longer duplicates surface description code into vertex shader.
