Textual dev (#2884)

* WiP: Move the devtools and related code to `textual-dev` (#2834)

* Remove the textual script from the project file

This is moving into the textual-dev package.

* Remove the textual CLI code from Textual

This has all gone to live in textual-dev.

* Remove the devtools testing from Textual's unit tests

They've moved over to textual-dev instead.

* Remove the devtools server from Textual itself

The start of the process to remove as much of the core devtools as possible
from Textual.

* Switch the console docs example screenshot over to textual_dev

* Remove rednerables.py from Textual

* Remove the last parts of devtools from Textual

This is the last step. It remains to be seen if this is sustainable, but for
testing purposes this is the extreme case we're aiming for. I *think* this
will work though.

Hereon we'll be needing to do an editable install of textual-dev into
textual, and more generally and once this is "live" we'll be needing to make
sure that textual[dev] is installed when doing development work on textual
apps.

The thing that remains to be seen however is how this all works
with *developing* Textual itself. Will I always need to do an editable
install? Still got to figure that one out.

* Start to whittle down the pyproject file

The next step is to try and work out what can come out of the pyproject
file.

* Remove aiohttp from Textual

* Remove some more development dependencies we don't need any more

* Relock

* Remove the pointer to the previews directory

* Reintroduce the border preview snapshot test

* Reintroduce the color preview snapshot test

* Reinstate the key press for the border preview snapshot test

* Reintroduce the easing preview snapshot test

* Reintroduce the keys tool snapshot test

* Add pytest-asyncio as a development dependency

* Relock

* Pin the textual-dev version to 0.1.0 or later

Mostly to try and get the tests kicked off properly.

* Relock dependencies

* Further `textual-dev` changes (#2850)

+# Textual 0.27.0 refactors dev tools
+
+It's been a slow week or two at Textualize, with Textual devs taking well-earned annual leave, but we still managed to get a new version out.
+
+<!-- more -->
+
+Version 0.27.0 has shipped with a number of fixes (see the [release notes](https://github.com/Textualize/textual/releases/tag/v0.29.0) for details), but I'd like to use this post to explain a change we made to how Textual developer tools are distributed.
+
+Previously if you installed `textual[dev]` you would get the Textual dev tools plus the library itself. If you were distributing Textual apps and didn't need the developer tools you could drop the `[dev]`.
+
+We did this because the less dependencies a package has, the fewer installation issues you can expect to get in the future. And Textual is surprisingly lean if you only need to *run* apps, and not build them.
+
+Alas, this wasn't quite as elegant solution as we hoped. The dependencies defined in extras wouldn't install commands, so `textual` was bundled with the core library. This meant that if you installed the Textual package *without* the `[dev]` you would still get the `textual` command on your path but it wouldn't run.
+
+We solved this by creating two packages: `textual` contains the core library (with minimal dependencies) and `textual-dev` contains the developer tools. If you are building Textual apps, you should install both as follows:
+
+```
+pip install textual textual-dev
+```
+
+That's the only difference. If you run in to any issues feel free to ask on the [Discord server](https://discord.gg/Enf6Z3qhVr)!
