This decouples the need for a published image for the bulid scripts and
will now embed them into the binary instead. This will make it so that
anyone that forks the CLI is able to make adjustments to the build
scripts and use them immediately.
This will be needed for testing #515
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/
```
