Better UX for Project Name changing

This is follow up for issue #108 .

When doing shore project init and giving the project name, the output that contains the project's name might be mutated - for instance stripped of various characters.

Especially in the case of a Spinnaker backend, the application and pipeline names both mutate the project name in different ways.

While we know this is to compile with how Spinnaker likes its' application and pipeline names - to someone that's unfamiliar, this may seem odd/confusing (why has project name been mutated, and it happened differently twice).

We should provide some sort of output saying "Hey we will mutate the project's name to compile with the backend", maybe provide how they will be mutated, or even the regex for mutation. This way it will not be a surprise to give a project name and then see it mutated in the output.
