support setting WP_ALLOW_MULTISITE

[guss77]

refactor the additional PHP code for wp-config.php into a function to support more complicated setups, and implement support for setting WP_ALLOW_MULTISITE

I don't think including hebrew (or other languages) into the official image is something we should do. You can easily do this by building your own image FROM the official image and adding the language files there.

IMO, this is pretty similar to #8 (and I'm really sorry for the delay in responding 😞); my reservations about it would be the same as those I have on #8 -- it's not included in the default wp-config.php file, so our script gets even more fragile than it already is by trying to support these types of things (which are more easily and support-ably accomplished by "bring your own config" either through bind-mount or through a derived image FROM this one which modifies the sample config we source). I do think we could do with better documentation around customizing the WP install, especially with regards to wp-config.php but even things like themes (or using a bind-mount for quick and easy theme development, for example).

This is useful, but not necessary if docker-entrypoint.sh would allow pulling in external snippets (i.e. from /etc/wordpress/*.php).

Why is it not merged yet?
