Add template renderas empty

[rullzer]

Richdocuments renders all their templates as empty. This is done because we embed the view in an iframe and we do not need the top bar etc etc.

This works because the old code never checks the render as value as being one of the valid ones.

I'd vote to make this an official mode. And then also make sure that we kill javascript that doesn't belong there (for example the search stuff).

GitMate.io thinks possibly related issues are #5534 (Empty trash), #10128 (Add locale to templates), #9529 (Template file), #74 (Add Automatic Tagging), and #6553 (Add public page template for apps).

So then there are 3? '', 'blank' and 'empty' ?

I'd vote for "add constants and unify the usage", because f#$k magic strings 😎

And btw blank and empty are used since 4+ years:

server/lib/public/AppFramework/Http/TemplateResponse.php

Line 149 in 0655df0

$renderAs = $this->renderAs === 'blank' ? '' : $this->renderAs;

Yes lets add them as constants!

Also if they are there already we should exclude some js loading on blank and empty etc.
