option to skip meta tag generator

[Sena]

With this option we allow the dev choose if they wanna show this meta tag or not

[rjd22]

👍 I would also like this option.

@DirtyF can you help this PR

I like to have this option. But I prefer something more general which allows you to disable any of generated tags. Like {% seo generator=false %}

Ref #355 #396

Skip generator meta tag is a good idea (or at least doesn't show version).

It's well-known to be used to know if site has any vulnerability.

The less information is given about frameworks, application servers, libraries ... the better.

[davorpa]

Could you change it by

{% unless seo_tag.skip_generator %}

It's more general

Unit tests must be also provided to check right working

Should we simply leave out the generator tag completely?

Any solution on this?
