This patch does two things:
- If there is no URL to download new data from, then the
Refresh button is not shown.
- Even if for some reason refresh starts for a client for
which there is no URL, loading correctly finishes.

This adds a number to the extension.

Note that for DownloadManager to keep this, the server
needs to send it a mime type it does not recognize. Right
now, it does not recognize application/json so it's okay,
but we'd do well to remove the content/type header from
the server to prevent problems.

What do you mean "Can't happen"?
It happens all the time - the empty string is the default ID, and it
needs to be updated like everyone else.

Upon invoking the settings of the dictionary pack with an unknown
client, we now launch an intent to ask the client to make itself known.
This change also includes the code that receives this intent and
acts upon it.
