Major Update

Using edgee:slingshot vs previous uploader.

Now, to use FileUpload fields, you’ll have to do:
meteor add quietcreep:formation-file-input-blaze

Then follow readme in Slingshot to create a directive for uploading;

Finally, the previous “uploadTo”, “bucket”, and “type” arguments to
FileUpload have been replaced by the “directive” param which is a
string, the name of the Slingshot directive you intend to use.
