Support json template literals (without templates)

[madeso]

Let strings contain multiple lines.

Template literals are enclosed by the back-tick ( ` ) (grave accent) character instead of double or single quotes.

`string text`

`string text line 1
 string text line 2`

Such a feature would aid in writing code in a json file.

• How should whitespace be handled? Remove existing indentation to the second line 'string text line 2' doesn't have a huge indentation because of it was nested deep?
• Is this potentially already solved by json allowing newlines in strings?
