Models locations should not be "hard-coded"

[girardinsamuel]

For now it's assumed in some places that models are located in "app/models". In some places we can edit the model path such as in the tinker command where with the -d flag we can change the directory from which models are loaded.

It's fine, but it would be better to have a configurable location as for other features of the framework. We could register something like this in the kernel:

self.application.bind("models.location", "app/models")

and be able to edit it later.

• [ ] register location for models
• [ ] use it where models path are hard-coded
• [ ] edit cookie-cutter kernel file
