fix enable and disable when selectbox destroyed

[bogdanRada]

This pull request is a continuation of this pull request https://github.com/marcj/jquery-selectBox/pull/150

Seems if the selectbox is disabled and then destroyed, if the selectbox is not enabled and you want to set options on the select and then enable it, seems the attribute "disabled" is not removed.

You can test this here: http://jsfiddle.net/xx97so9m/1/ ( using master branch from github) - This is a demo of the bug .

If needed i can make a demo with the fixed version too.

This solves this issue.

Please let me know what you think. There might be a better way of doing this. Thank you very much
