Support jQuery UI 1.11

[rxaviers]

This issue is only a checklist reminder of 1.11 changes download.jqueryui.com needs to support:

• Give puff-effect and size-effect its own files. Previously, into scale-effect file. jquery-ui#981
• Effects (core): Unite demos into the same single effect/ path jquery-ui#982

+ Milestone: https://github.com/jquery/download.jqueryui.com/issues?milestone=3&state=open

One more pre requisite: #179

Added AMD support issue in the check list.

I'm closing this "milestone-issue", and instead using a milestone to track the issues left (note that issues left now are from our own repo).
