Summary of Changes

Subform repeatable has a function fixScripts which calls a few js initialization functions on a few of the field types that require it. There is a now a better way to handle that kind of thing by having any field that may need initialization listen for an event fired by subform repeatable. In this PR, I am transferring responsibility of one such initialization from subform repeatable to the correct field type itself.

Note: this PR doesn't really fix anything. Fields that use squeezebox already work with repeatable subforms. This just does it in a somewhat better way.

Another note: Squeezebox uses mootools and is deprecated. Bootstrap modals are prefered. Still, as long as some fields use it, they should use it like this.

Testing Instructions

Set up a subform containing a field that uses squeezebox (for example contenthistory). There's a subform in the redirect plugin that's simple to use for this purpose.

Open up the form and create new rows. The field in each new row should function properly.

Expected result

Fields that use squeezebox function normally.

Actual result

Fields that use squeezebox function normally.
