Update Resources/dropbox.js

Consulting the SDK iOS Dropbox, and more specifically the file for DBSession in iOS, I found that in API url is formatted in the format "%@://%@/%@/connect_login?k=%@&s=%@&easl=1%@"
If, therefore, in webview uses this url to log in, you will see the same login page of the iPhone, then no other link :)
Login iPad without link

If you use this module with iPad, the login page contains links that are not allowed by Apple, threatening to have rejected the app.
But we can add "display = mobile" in the query params of the /oauth/authorize url to force it to display the mobile oauth flow. In this way, it is as if we access with the iPhone.
I already tried, and is fully compatible with the module.
