 Thinking we ignore FTP?

 Been thinking what we can do in these cases. One possibility is
 translating from JS (similar to how TinyMCE does it). On page load we do a
 JSONP request that returns an translation object `{ 'English string':
 'Translated string', ... }`. Then we walk the DOM and replace (may wrap
 all strings in something like `<span class="wp-translate">` to make that a
 bit easier/faster). This may make the page flicker a bit.

 Another (better?) possibility would be to get an installation-only .mo
 file from the WordPress.org API on each request and use it directly (keep
 it in memory). Yes, it's expensive and will slow down the 3-4 page loads
 while installing, but would work in all cases.

 This can also be used on the FTP setup screen (right after we are up and
 running) so the user can install the language pack.
