Add an unlimited number of custom code generation tasks
Previously when you generated code, you got for each model in your project a code generation task: one for the entity model,
and one for each derived model you have in your project. Starting with v5.7 you now can add custom additional code generation
tasks for a model, without limits, and additionally code generation tasks which target the whole project.
This allows to e.g. generate documentation for the models in your project, to add custom templates
to generate service code or e.g. an ASP.NET website, without touching the shipped presets and templates.
