A changelog list

[trygvis]

For clients that download lists (for offline use) having a change log that lists all items of a particular type would be useful.

Suggested API:

In the start resource, have a query like this:

{
  "href" : "..",
  "rel" : "changelog",
  "prompt" : "Enter search string",
  "data" :
  [
    {"name" : "type", "value" : "<rel>"},
    {"name" : "from", "value" : "<from date>"}
  ]
}

Don't know if using rels as a type identifier is a good idea, but it'll work.
