Sharing of Files not fully downloaded shouldn't be sharable

[Tom Gall]

Via the U1FilePreviewViewController one can share a file even tho it's still not fully downloaded. If I download a jpeg for instance, and select to share it with another app before the download is complete, an incomplete jpeg will be handed off.

Via the U1FileDetailViewController trying to share a file not downloaded will cause simply no action to occur.

The share button should be gray'ed out and in the U1FileDetailsView it should note if the file is local or not with an option to pull it down if it's not already local.

Likewise U1FilePreviewView should not allow sharing if the file is not downloaded.

Overall there should be an option to delete local copies of the file which are in the cloud as well as locally to save space without actually deleting the file.

Moving the last paragraph/comment to a new bug, but the rest is being acted on.

Actually, not. We've got roadmap features for a gesture to pin/eject files for download. When we get there, that behavior will exist. But I will disable the share button until the file is downloaded.
