Dropbox support added to Linklok

We have added Dropbox support to all versions of Linklok. This works in a similar way to our Amazon S3 support. Linklok can generate secure download links that download directly from Dropbox. Users don't need a Dropbox account to download of course.

Amazon S3 V4 Signatures are now supported. V4 Signatures are required by buckets in some new regions such as Frankfurt.

Sitelok passwords (where supported) are handled more securely now with an option to only display them when a new Sitelok account is created. After this the password can be starred out or some specified text can be displayed instead.

Linklok URL now has the ability to save form submissions to Sitelok. This allows you to keep in email contact with contacts.
