'x' in modal close renders as strange capital A and hyphen

[phil-dileo]

replace x with × here

angular-prompt/dist/angular-prompt.js

Line 109 in 6de8bdf

" <button type=\"button\" class=\"close pull-right\" ng-click=\"$dismiss()\" aria-hidden=\"true\">×</button>\n" +

Note: this is what bootstrap does http://getbootstrap.com/javascript/#static-example

I can submit a pull request for the small change.
