jio get API changed: jio.get("id"); -> jio.get({"_id": "id"});
jio putAttachment API changed

// Before:
jio.putAttachment({
  "id": "docid/attmtid",
  "data": "abc",
  "mimetype": "text/plain",
  "rev": "xxxx"
});

// Now:
jio.putAttachment({
  "_id": "docid/attmtid",
  "_data": "abc",
  "_mimetype": "text/plain",
  "_rev": "xxxxx"
});
jio get: "_rev" is required in the document, no longer in the options.
jio.js updated
