1.13 not compatible with jquery 1.9 due missing $.uniqueSort

[glensc]

Uncaught TypeError: $.uniqueSort is not a function
    at processClassString (jquery-ui.js?id=44a2af31b10434ff00c4:3226)

See eventum/eventum#1256,
and eventum/eventum#1240 discussion

But the 1.3.0 release post says jquery 1.8+ remain supported:

Support for jQuery 1.7 has been dropped; jQuery 1.8 & newer remain supported.

Seems the compat was added to jquery-1-7.js file:

• 0b7246b

which was later removed

refs:

• [1.13] Feature/remove some jquery 3 migrate warnings #1773
• Replace unique by uniqueSort #1801

We renamed the file to jquery-patch.js; see the relevant portion of the upgrade guide.

This should be all you need to let me close the issue. If there's something I missed, please add a comment & I'll reopen. Thanks!
