vcreate: re-prompt on invalid project name instead of exiting

[ttytm]

Assuming that someone still wants to create a V project after entering an invalid project, this change still prints the error but re-prompts for a project name input instead of exiting the project creating process. This spares executing the v new command again.

Make vcreate more interactive by prompting for a new project name if the input is invalid or existing. Update vcreate.v to implement this behavior.

Do you think you can implement test as well?

When finding a free moment, I'm gonna test if implementing a test is not too big of a hassle to give a better answer to this 👍

[ArtemkaKun]

Sure, if we have no infrastructure for tests of vcreate and implementation of it will be an enormous task - better to focus on something else I believe

That is error prone:

Imagine if someone enters an invalid name like ---, then an invalid name again, etc.

With the previous behavior the early exits will make him always go back to the start, and hitting "up arrow" in the shell is not hard at all.

With the current changes, if you repeat entering an invalid name, eventually you will pass all the checks, and then fail later at creation :-( .

[spytheman]

I think that leaving the repeating to the shell, which is a tool, that specializes in making that more convenient, is more robust, than implementing it piece by piece in the project creation tool, whose main goal (generating lots of boilerplate) is far from it.

Good point. Thanks for the review @spytheman.

It could be solved by using a recursive check function. If that's a thing that would consider.
