decal atlas support work

Browse source 
allow a textureCoordCount to be used raw when texrows and coumns are not >1 in order to let the transmitted vector actually be used

correct and augment editDecalDetails to now read
      DecalEditorGui.editDecalDetails( %this.instanceId, %pos, %tan, %size, %uvID  );
it needed the word split to begin with, and also added the uvID for instance frame tracking/overriding
same token added a  getDecalFrame(%this.instanceId); method

todos: add a frame lookup and selector for the instance tab, modify decal display to account for non-square uv portions
