Add support for dumping build system state in JSON format (GH issue #182)

Specifically:

1. New --dump-format option. Valid values are `buildfile` and `json-v0.1`.

2. The --dump option now recognizes two additional values: `match-pre` and
   `match-post` to dump the state of pre/post-operations. The `match` value
   now only triggers dumping of the main operation.
