[Feature] Generate .gitignore and IDE settings whenever necessary

[ahaim5357]

One of the useful things to do when generating a new project or patching an existing one is to provide a .gitignore or addition IDE settings suited to their needs.

For this project in particular, the .gitignore should be generated for hiding src and clean directories alone with any potential caches.

Additionally, we can add IDE settings for those which support json schemas to add the relevant links and validators.

This can probably also be extended to dockerfiles.
