Add file information to boilerplate

[DG-7D]

What I can't do right now, that I would like to
Add filename and build date/time to boilerplate.

Why do I want to do this thing
I can easily know which code the vehicle is using and if the code is up-to-date.

What I think the solution would be, and how it should work
Add some variable like $date, $time and $filename to Extended Boilerplate setting

Why I can't use an existing/alternate solution
Writing them manually is very dull.

It's a good feature idea.
I'm afraid I'm personally out of time to work on non-critical stuff right now - but by all means if you implement it, please just Pull Request it and I'll stick an update out.
