Add names and plain_names fields.

+* The `--name` and `--plain-name` arguments may be passed more than once, and
+  may be passed together. A test must match all name constraints in order to be
+  run.
+
+* Add `names` and `plain_names` fields to the package configuration file. These
+  allow users to control which tests are run for the given presets.

 ## 0.12.12
 
 * Add support for [test presets][]. These are defined using the `presets` field
   in the package configuration file. They can be selected by passing `--preset`
   or `-P`, or by using the `add_presets` field in the package configuration
   file.
 
 * Add an `on_os` field to the package configuration file that allows users to
   select different configuration for different operating systems.
