Kevin Brown 5ec201ca30 Built out the translations
This migrates over the required English translations under their
new names.

The "Searching" message has also been adjusted to use "Searching..."
instead of "Loading more results...", which is what it used to
say sometimes.

This also changes the AJAX handler to call `abort` when needed.
