refactor(tools): move most tools to the engine

[RiscadoA]

Description

So this PR looks big and scary but it's nothing ground breaking - I didn't implement any features here.
I just moved most of the tools in Tesseratos to the engine, under the directory tools.

Previously, Tesseratos was a library, which meant we could just use its utilities in games (such as Scraps vs Zombies) by linking Tesseratos as a dependency.
With 0.3, Tesseratos became an actual executable, which meant its tools became inaccessible.
The goal here is to simply move the tools which can be useful even in a deployed game to the engine library itself, while keeping actual editor stuff, such as the asset explorer and scene editor, on the editor itself.

I had to change a lot of boring stuff, such as the namespaces of everything from tesseratos:: to cubos::engine::, and also the respective documentation. Also used the opportunity to reword some stuff better, and simplify the naming of some plugins.

Also, to make things easier for users, I added a toolsPlugin which simply adds all of the plugins in the new directory.

Checklist

• Self-review changes.
• Evaluate impact on the documentation. (I had to change a lot of stuff!)
• Ensure test coverage. No new features.
• Write new samples. No new features, although I added the tools to the CuboSurfers plugin.
• Add entry to the changelog's unreleased section.

I wasn't familiar with how this was organized before, but these changes seem to centralize all the tools, making it easier to use them. lgtm
