DELETE for attachments

[DiegoJArg]

While starting to discover CouchDB and Fauxton, it is easy to add attachments, but an attempt to delete them seem to not be as easy as expected.
I don't really know what is happening and the error message doesn't really shows much.

Expected Behavior

Click somewhere in Fauxton to delete the attachment.

Current Behavior

curl -X DELETE http://admin:secret@localhost:5984/couchproducts/_design%2Fcouchproducts/myfile.zip
{"error":"conflict","reason":"Document update conflict."}

curl -X GET http://admin:secret@localhost:5984/couchproducts/_design%2Fcouchproducts/myfile.zip?revs_info=true
Returns nothing

"_attachments": {
    "myfile.zip": {
      "content_type": "application/zip",
      "revpos": 4,
      "digest": "md5-AiwXFik75/GtK89+z/7ItQ==",
      "length": 46892239,
      "stub": true
    },

Possible Solution

Feature to list attached files and be able to delete them.

Steps to Reproduce (for bugs)

1. Create a document
2. Attach a big file
3. Watch how this expand the size of the database
4. Try to delete it to reduce the size of the database

Context

I was trying to learn more from CouchDB as a beginner.
The attempt was to check if attachments were stored as files or documents, or inside the database as blobs.
It turns out that they are stored as blobs.
Now I want to delete it and while Fauxton doesn't have the tool to do it, it is rejected by curl.
