Cujo: drop transition

This isn't in the spec and didn't add any value.

examples/cujo/app/main.js

 /*global define */
 define({
-	// Cujo uses OOCSS principles and thus separates theme (skin)
-	// from structure CSS.
-	theme: { module: 'css!theme/base.css' },
-
 	// The root node where all the views will be inserted
 	root: { $ref: 'dom!todoapp' },
 

examples/cujo/theme/base.css

-#clear-completed {
-	transition: all .1s ease;
-	-webkit-transition: all .1s ease;
-	-moz-transition: all .1s ease;
-	-ms-transition: all .1s ease;
-	-o-transition: all .1s ease;
