  Move shader variables header to include folder.
  
  This allows the API to query for clear type introspection into the
  parsed GL types from the translator. The returned types are not
  expanded and have properly nested fields.
  
  This patch uses the types from ShaderVars.h to return GL type
  information. The app must include this header to get access to
  the types structs.
