[Building Sakai] Javascript Libraries

[Charles Severance]

Unfortunately the problem is that as JQuery goes through its 1.x and 2.x versions, they keep finding "better" ways of doing things and so they break old ways of doing things.  So an upgrade from JQ 1.6 to 1.9 will likely break several things.

Interestingly, there always seems to be a trivial workaround for their removed features - but they don't want to keep the old way working.

So having one central JQuery version would be a great idea - but then when we upgrade it - stuff will break all over the place across core and conrtib.   I did just a bit of experimenting with this when I was playing with removing iframes - and it is quite frustrating.  

We should come up with a central place to manage this for those tools that are willing to stick with the same version as portal - currently  jQuery 1.9.1 and jQuery-UI 1.10.3 as Sam mentions and then me really mindful when we change the version.

I have a feeling this will come to an even more painful head when some Sakai tool decides it loves JQuery 2.0 and we don't have frames any more and then we will break a *ton* of stuff. 

If it were up to me, once we get to JQuery 1.9.1 across the core, I might suggest that we freeze the JQuery version for a year or two.

I so wish JQuery would give us a set of backwards-compatibility libraries at the cost of a little more code.  But they are like "WE ARE JQUERY - YOU WILL BOW BEFORE OUR GENUIS".
