Add stub pages and oauth-blessed request to /newui

appengine/swarming/elements/README.md

 This contains all the Polymer 1.X elements used in swarming.
+
+To clean and build the pages for deploying, run
+
+    npm install   # Need to only run once to set up dev dependencies.
+    make vulcanize
+
+This combines all of the elements needed to display the page into several "single-page" apps, like
+the bot-list.
+These are checked into version control so that they may be easily redeployed w/o having to rebuild
+the pages if there were no changes.
+
+
+To do a full clean rebuild, run
+
+    make clean_vulcanize
+
+
 To access the demo pages on localhost:8080, run
 
-
     make && make run
