feat: Look for recipes in ./recipes/, build files in ./files/, and Containerfiles in ./containerfiles/ (#157)

Recipe files can now be put into their own directory `./recipes/`. This
directory is NEVER copied into the build so changes to a recipe will no
longer cause cache misses for builds. Here is an example of my build
changing the second to last module and only requiring the last 2 `RUN`
layers to be run again.

```

```

Support was also added to put all build files into `./files/` instead of
`./config/`. This is an all or nothing operation, meaning if there
exists a directory of `files` then the `config` directory will be
completely ignored. Work will have to be done in
https://github.com/blue-build/modules to allow users to put their files
directly in `./files/` and not `./files/files` for the `files` module or
`./files/scripts` for the scripts module.

Support was also added to move the `./config/containerfiles/` directory
to the root of the project. Now the directories you can find in the root
of projects are:

```
files/
containerfiles/
recipes/
```
