Provision the WordPress i18n Tools.
Stick a convenience shellscript in the `homebin` so we don't have to provide a path to `makepot.php` all the time.
Revert "Provision the WordPress i18n Tools."

This reverts commit c2b06899e72a2fa0dbdf5b7bbea4c856be910ba2.
`gettext` is required by the i18n tools.
Switch to reference the i18n tools in `/srv/www/wordpress-develop/tools/i18n/` in `make pot`.
Consistent use of strings in provision.sh

Use echo in favor of printf to not have to add \n each time; use quotation marks around strings consistently; minor string changes
Use `-e` flag to enable interpretation of backslash escapes

We do use `\n` from time to time for additional spacing around lines. `echo` does not handle this by default until a flag is used to do so.

Refresh, update, and document Nginx configuration

Thanks to some excellent reading provided by H5BP in their [nginx server configs repo](https://github.com/h5bp/server-configs-nginx/blob/master/nginx.conf), I was able to clarify and better document a few of the settings in our Nginx configuration as well as add a couple other directives.

Things seem to be working fine currently, please open up an issue if you start noticing weird Nginx behavior
Update to phpMyAdmin 4.0.5
Fix for Nginx 502 error: `upstream sent too big header while reading response header from upstream`
Fix typo in inline doc. Was changed 6 months ago, see 457bf30d
Merge remote-tracking branch 'simonwheatley/bugfix/502-response-headers'

Work toward PR# 135
Further document the fastcgi_* directives in nginx-wp-common.conf

Closes #135
Specify a charset of UTF8 in nginx-wp-common.conf
Document the try_files directive in nginx-wp-common.conf
Remove duplicate client_max_body_size directive from nginx-wp-common.conf

We already specify a client_max_body_size of 50M in nginx.conf. Having it in our common WP file as well makes it harder to overwrite the setting at an individual site level (I think).
Merge remote-tracking branch 'ocean90/patch-1'

Thanks @ocean90!

Closes #137
