--json-exceptions
Added a --json-exceptions option, which makes some exceptions be output in json.

The distinction is that --json-error-messages is for messages relating
to a particular ActionItem, while --json-exceptions is for messages that
are not, eg ones for a file that does not exist.

It's unfortunate that we need two switches with such a fine distinction
between them, but I'm worried about maintaining backwards compatability
in the json output, to avoid breaking anything that parses it, and this was
the way to make sure I didn't.

toplevelWarning is generally used for the latter kind of message. And
the other calls to toplevelWarning could be converted to showException. The
only possible gotcha is that if toplevelWarning is ever called after
starting acting on a file, it will add to the --json-error-messages of the
json displayed for that file and converting to showException would be a
behavior change. That seems unlikely, but I didn't convery everything to
avoid needing to satisfy myself it was not a concern.

# NAME
git-annex dropkey - drops annexed content for specified keys
# SYNOPSIS
git annex dropkey `[key ...]`
# DESCRIPTION
This plumbing-level command drops the annexed data for the specified
keys from this repository.
This can be used to drop content for arbitrary keys, which do not need
to have a file in the git repository pointing at them.
Warning: This command does not check that enough other copies of the content
exist; using it can easily result in data loss.
# OPTIONS
* `--batch`
Enables batch mode, in which lines containing keys to drop are read from
stdin.
* `--json`
Enable JSON output. This is intended to be parsed by programs that use
git-annex. Each line of output is a JSON object corresponding to a key
being processed.
* `--json-error-messages`
Adds an "error-messages" field to the JSON that contains messages that
would normally be output to the standard error when processing a key.
* `--json-exceptions`
Output additional JSON objects for some exceptions that are not
associated with a particular key.
* Also the [[git-annex-common-options]](1) can be used.
