Wrong redirect URI on dropbox

[Gyran]

I'm guessing the extension will have different keys on other peoples computer so the Dropbox redirection will supply an error. If it does supply the error message in a comment to this issue and I will add it to the allowed redirection list.
I will try to get the App ready for production status so I can publish the extension in the Chrome Web Store to get a permanent extension key, but in the meantime this will have to do.

Should be fixed now with the key entry in the manifest in 8acdb8b
