chosen dropdowns, class chosen not set

[jberculo]

Could there be an issue with the chosen dropdowns? I've got two installs, and on both the class "chosen" is not set, so the dropdowns are not initialised.

I had problems with the "normal" DropdownField too.

I think it's because of the newly added BootstrapDropdownField(.php/.ss) which results in a DropdownField always being rendered with BootstrapDropdownField.ss (in your case: where $extraClass is not added to the select tag and the select tag is wrapped) even if i don't want that button/dropdown/toggle functions.

BootstrapFieldList.php line 55
$bootstrapCandidate = "Bootstrap{$className}"

Some other features weren't working as expected either (setEmptyString or setSource or Dropdownfield not working correctly with BootstrapDropdownField.ss and BootstrapDropdownField missing some features)  - I don't remember exactly.

I wanted to add the bootstrap-select library (https://silviomoreto.github.io/bootstrap-select/) myself so I had to override the BootstrapDropdownField.ss template to get the standard DropdownField rendered (copied silverstripe-framework/templates/forms/DropdownField.ss and renamed it to BootstrapDropdownField.ss). Maybe this workaround works for the chosen-dropdown as well.

Maybe the BootstrapDropdownField class and template should be renamed to BootstrapSelectDropdownField (or similar) to avoid those conflicts?
