Fix for Nginx 502 error: `upstream sent too big header while reading response header from upstream`
Stick a convenience shellscript in the `homebin` so we don't have to provide a path to `makepot.php` all the time.
`gettext` is required by the i18n tools.
Switch to reference the i18n tools in `/srv/www/wordpress-develop/tools/i18n/` in `make pot`.
