Have themes use CDNs for YUI, JQuery, Bootstrap?

[Glen Mazza]

Hi team,

I had given a suggested JIRA to Gaurav: 
https://issues.apache.org/jira/browse/ROL-2020 for him to factor out the 
Bootstrap/JQuery into the webapps/roller-ui folder so multiple themes 
can take advantage of it, i.e. the user wouldn't need to manually import 
that library with his theme.  Providing that option would probably still 
make sense.

I guess though I am behind the times with that suggestion, apparently 
our themes should be using content delivery networks to download the 
libraries instead of the server hosting Roller?  YUI would be something 
like: http://yui.yahooapis.com/3.17.2/build/cssreset/cssreset-min.css, 
JQuery would be http://code.jquery.com/, Bootstrap would be: 
http://www.bootstrapcdn.com/.

Apparently the main benefit of using CDN's is that it drops demand on 
the server hosting Roller, making it cheaper for someone to get Roller 
hosted and also making it more attractive for hosting companies to offer 
Roller.  However, a drawback is YUI doesn't offer SSL support for 
philosophical reasons 
(http://yuilibrary.com/yui/docs/tutorials/faq/#does-yahoos-cdn-support-ssl) 
That might not be a big deal for us, because the blog reader doesn't 
need SSL as he's not sending any private data and even if the blog owner 
uses SSL to keep his password encrypted on the wire, not much else needs 
to be secure so going to the CDN for a few JavaScript libraries wouldn't 
be a big deal.

I guess we'll continue storing the Javascript libraries that the themes 
need, but in the future would it be a better design to have the themes 
using CDNs?  WDYT?

Regards,
Glen
