Please include $config->defaultAdminTheme and option to include setlocale()

Opening an issue in this repo to to continue the discussion started here: https://github.com/processwire/processwire-issues/issues/451

... it is not possible to export $config->defaultAdminTheme = 'AdminThemeDefault' in /site/config.php using the Site Profile Exporter. That's because so long as that setting remains in /wire/config.php the Site Profile Exporter does not recognise it as a customisation to be included in the export - only config values that differ from those in /wire/config.php may be exported.

And could you also allow Site Profile Exporter to include the setlocale() setting in /site/config.php? This would help to minimise the number of things I have to remember to manually add/override for new installations.

Would be cool to be able to apply any custom configurations, as they are common and make a significant part of profile settings. But is that even possible, @ryancramerdesign ?
