fix($build): Stop jQuery plugin from being concat twice

Only affected using jQuery + S3
fix($build): Include ui.handler.click.drc.js

Prevents user's ability to 'cancel' or 'retry' an upload.
Originally, this was not included unless the user chose both UI and Delete
as part of their build.
refactor($build): Load JQuery plugins last
fix($qq.hasAttribute): Better "false" detection

qq.hasAttribute was returning `false` if the string "false" was
present anywhere in the attribute's value.

Now, qq.hasAttribute will only return `false` if the entirety
of the attribute's value is "false" (case insentive, as before).
