Implement basic HTML form for Person type

[literarymachine]

Task for #22 & #23

[acka47]

Both peoperties "description" (https://github.com/hbz/oerworldmap/blob/master/public/json/schema.json#L525-L527) and sameAs (https://github.com/hbz/oerworldmap/blob/master/public/json/schema.json#L569-L575) are part of the "Person" schema. They are not shown in the HTML form, though.

Fixed on beta & production.

Regarding #452, we should remove affiliation from the web form and add memberOf instead.

Several times I had problems with an email I copy&pasted from a google spreadsheet. Everything would look ok but when I click on save there would be the following error message:

When I type in the same email, everything is fine and the edits can be saved.

[literarymachine]

There seems to be an illegal character in the copied content then (probably a newline character, which is not valid in email addresses). We are using your browsers HTML5 support for validation here, more specifically the email input type. Not much we can do about that.

[acka47]

So we don't have influence on the wording of the error message?

[literarymachine]

We could - but a newline is an invisible character nevertheless. On top of that, setting custom validity will only work for users with Javascript enabled, so this cannot be part of the current basic versions of the forms.

What I meant was showing a rather generic error message as this seems to be wrong or at least confusing. You can easily read it like: We don't want a period . before an @. Thus, a general message like "Oups, something went wrong. Please again type in your email address." would be better.

Whatever the message is, we would have to overwrite the browser settings, and this needs Javascript. So, like I said, this is not possible in the non-Javascript base forms.
