[16.11.1] Added new themes for invoices, quotes, orders, receipts etc

I need the adjustments in code to only apply to Invoice as i notice that when i go to other forms the changes have been made on them too. (As designed i believe)

When Invoices have been created using different Themes i need that particular Theme to stick to the corresponding invoice so when i go back and view an invoice the correct theme is showing.

If you want some information to be shown on document only if {{ title }} is Invoice, then you can use simple conditional block.

{% if title == 'Invoice' %}
This text will be shown only if title is "Invoice"
{% endif %}
