v0.147.0

This release comes with a new `aligny` option (shoutout to @pranshugaba  for the implementation) for [images.Text](https://gohugo.io/functions/images/text/) that, in combination with `alignx` makes it simple to e.g. center the text on top of image in both axis. But the main reason this release comes now and not later, is the improvements/fixes to the order Hugo applies the default configuration to some keys. This is inherited from how we did this before we rewrote the configuration handling, and it made the merging of configuration from modules/themes into the config root harder and less flexible than it had to be. Me, @bep, looking into this, was triggered by [this](https://discourse.gohugo.io/t/how-to-manage-common-config-in-hugo-using-modules/54485/4) forum topic. Having many sites share a common configuration is very useful. With this release, you can simply get what the thread starter asks for by doing something à la:

```toml
baseURL = "http://example.org"
title = "My Hugo Site"

# ... import any themes/modules.

# This will merge in all config imported from imported modules. 
_merge = "deep"
```

See the [documentation](https://gohugo.io/configuration/introduction/#merge-configuration-settings) for details.
