Support of upload office documents in chat room

[steedos]

Currently, only images are valid to upload. and there is a bug, if i drag a file to the window, it will ignore the file extension check.

Also, it's need the admin settings for documents size limit.

There's already an issue for setting of max upload file size: #756.

• Create Admin setting to define if uploads are enabled, allowed media types, max file size
• Change form validation to reflect newly-added setting
• Inspect/fix drag-and-drop upload

Go for it, we have an issue with anyone dropping a file into chat, it hang chat and you might actually lose connection to room.

It turns out the bypassing of files with different content types than those explicitly defined is related to an existing bug on jalik:ufs. I have created a PR to fix that (jalik/meteor-jalik-ufs#19), hopefully it gets accepted soon and we can leverage this fix.

I will put this on hold while we wait for a reply from the package maintainer. Otherwise we can add my forked version to our packages.

@gmsecrieru, thanks for the PR, I've accepted it and published new version of UFS packages (now also include the MIT LICENSE I forgot to add). I'm glad to see my work used and fixed by others ;-)
