These are the importers we suggest on import.php, prompting the user to
install the relevant plugin for the import they want to go through.
If the API is inaccessible, it falls back to a hard-coded list that should
be kept sync'd with the API with each major version of WordPress. This API
enables us to add new importers between releases, as they are completed or
if services gain quick adoption. As a last resort, we can also temporarily
disable importers that are broken (due to API changes, for example).
The importer currently returns English strings (which are then run through
translate() for existing strings), but the locale is passed to the API,
allowing us to ship translated strings if we wish to be adventurous.
props dllh for the assist.
