Support custom attributes

[kimisgold]

I'm looking to provide aria labels for chosen's text inputs to satisfy WCAG accessibility requirements, like in this issue in the original repository.

Steps to reproduce

1. Install the WAVE extension for Firefox or Chrome.

2. Run the extension on the Chosen demo page.

3. You should see all the form elements that require labels.

Expected behavior

I would love for an aria label applied to the original select carry over to the text input. Alternatively, I could pass a specific string to the Chosen call to label the text input, i.e. "Find options via autocomplete".

Me too. Some way to add an aria label would be great. It looks like it is currently making some effort to copy across aria-label. If I set it on the select, the input has aria-label="[object Attr]" added, so it's trying to do something, just not quite getting it right. But the ul also needs an aria-label and, perhaps more problematic, the ul should have children
