Allow attribute names to be escaped on ER diagram

[deniswsrosa]

Description

I have a few use cases for Document databases where I need the attribute name to contain special characters in the ER diagram. It would be really nice if we allow users to specify whatever name they want using backticks:

erDiagram
hotel {
String address
String geo.accuracy
}

Steps to reproduce

try to generate an ER diagram where the attributes have .,?, "" etc
