Most problems were due to strings being duplicated and overwriting each other. Updated the build-locales script to keep track of duplicates.
Project Curated by on the splash page was just missing the formatMessage call.
There is some stacking that happens in object keys that had been using the `-` to track language/view hierarchies, which was thrown off by view names that used a `-` in them. Switch to using `:`, and also make it customizable. Fixes#655
Before we were using glob, which was about to start failing on subdirectories in views (which we started using in `conference`). Instead of searching for `l10n.json`, it seemed more appropriate to instead look for localization by using the configured pages that need to be localized.
This moves all locale/translation building to a dependency, `scratch-www-intl-loader`, as well as tests associated with it. Also gets rid of the `make translations` step.
1. Load locale strings into `window._messages` in a separate file added to `template.html`, which contains view-specific and general strings
2. Update build-locales to compile separate files
