Restriction on file extension doesn't work

[patriciainimov]

Thanks a lot for this plugin. The only problem is that the restriction for file extension does not work.. For instance, when i put ['.pdf'] as value for ext, the selector still accept images and all kind of files. Am i doing this wrong? How can i solve this?

I solved the issue. It was due to the fact that i added restrictions on the extension using the '.', like this: ['.pdf'], this beacause i saw it in the doc on the readme file. I should be like this: ['pdf']. Maybe you should consider updating the readme file.

The option

let ext = ['*']; // Allow any file type.

This does not work either. I have fixed it in the PR: #4
