feature - per language configuration, and default tick to js/ts/md

[jeremychone]

Problem

As of now, there is only one quote sequence " -> ' -> ` which is not suitable for all language (especially the tick)

Solution

• Default the Tick to JavaScript, Typescript, and Markdown only.
• Allow customization with togglequotes.chars For example.

"configurationDefaults": {          
  "[csharp]": {
    "togglequotes.chars": ["\"","'","`"]
  }
}
