misspellings in minified & full dropify js

[ssayre]

There is a typo in https://github.com/JeremyFagis/dropify/blob/master/dist/js/dropify.min.js See: Ooops, something wrong appended

Oddly, this typo does not exist in the full dropify.js file. However, there is a spelling error in the dropify.js

• Ooops, something wrong happended. I expect this should read
• Ooops, something wrong happened.

i have solved the issue by adding style sheet in the page and it works fine.
