S3 Folder synch prefs bug

Dave Jones reports a problem on the Folder Synch prefs page.

I had seen the problem previously, and was able to reproduce the problem here.

The message says the problem is that it's not a number, but that of course is not the problem (we entered numbers). Here's the error message that the software is throwing: Can't coerce user.fileSynch.synchPoints.[%22Amazon%20S3%22].prefs.secsBetweenScans to an address because it doesn't specify a valid object in the database structure.

Obviously the problem is that the address is url-encoded. That is definitely not a legal object database address.

We need two versions of the address, one that's encoded and one that isn't.

Also, we weren't displaying the text to the right of the input box. Added that back.
