Accessibility: IndirectSelection Plugin

[jbest]

We had a screen reader company review our product. They flagged the IndirectSelection? plugin with a few minor issues.

Here is what needs to change:

1. The role needs to be checkbox
2. It is not aria-pressed, it is aria-checked

The presentation role is design for elements you want to hide from a screen reader. Here is a sample form a listbox:

<li role="checkbox"

aria-checked="true" aria-label="label1”>
