Bring back tool support?

[Dyhr]

PR #57 replaces the tool command with the plugin command, but forgets to make the plugin add command actually do anything.

As a first time user of dioxus, I was hoping that adding the tailwindcss was trivial, but this change and the fact that the documentation is not updated makes it not.

Given that the tool command is still referenced in the documentation and is still in the code, can we bring it back until the documentation is updated?

in my new PR, I've deleted all tools code, and I'm working on a new version plugin system.

I appreciate a new system, but why remove the old one before the new one is ready?

The old one wasn't sustainable (the Dioxus team couldn't support more than a couple of tools and make sure they work with the latest versions) and in my experience it didn't work that well either.

#124 fixes the plugin system and makes it usable, and we have an unofficial Tailwind plugin in the works here: https://github.com/DioxusPluginCommunity/tailwind-plugin
