Added safe_email filter for email field

[NicoHood]

Note: This requires grav 1.7.0-rc.18, as safe_email got fixed there:
getgrav/grav@068de42

Please have a look at #477 first. I will rebase afterwards.

Interesting... Hide emails in the forms...

[NicoHood]

It only hides the default emails.

Example:
I have a website that lists multiple businesses. I am hiding their email with safe_email filter.
Now I add a /edit page where you can correct the data. The emails are prefilled. Of course this page can be grabbed by bots too, so to should also have this filter applied.

I also wanted to add this for the telephone field afterwards.

Since the other PR got rejected: What about this one? I've simply copied the general field template, so everything should be still compatible. I know that emails are not iterable, maybe we can remove it in this field. What do you think?

I'm not sure how this will save after it has rendered with the safe_email filter applied?

[NicoHood]

I dont understand your comment, sorry...

The filter will just obfuscate the email. I am using this for every email on my webpage and I noticed, that prefilled forms are lacking this filter. It does not hurt to have it there I think.

When it’s prefilled obfuscated and you submit again, it will submit obfuscated right?

Imagine you have a user profile with email field. When the profile loads and the raw value gets manipulated to show the safe version of it, it means that if I save the profile again it will now be storing the value obfuscated (in yaml or wherever it’s going to be used).
This is hardly a wanted behavior, most likely now sending an email to that obfuscated email will result in an invalid address error and so on.

That’s the issue I’m taking about. Am I missing something?

[NicoHood]

It does not submit any obfuscated text. You can encode every html character like this. Did you try this? I guess you assumption was just wrong.

I'm going to test this one after the next release.

Any updates?
