Render a Blippa variable as EAN code

We have now made it possible to render a text variable as EAN code.

This only works in the editor.

Example:

$var:myvariable:barcode$

You can also specify what kind of EAN code to generate:

$var:myvariable:barcode:ean$
$var:myvariable:barcode:code39$
$var:myvariable:barcode:isbn$

etc.

Here is a list of all possible options and the corresponding EAN version.
