Identified external dependencies with js color palette

[daniellockyer]

• identifying external dependencies is useful because it enables you to
  differentiate between code in your project, and code that you import
  in
• this commit adds an if-statement to check for the node_modules/
  string, and colors it purple if found

Hey @jonhoo - ❤️ Inferno 🙂

I've tested this locally with a tool I'm writing for NodeJS and it produces the following:

As a reference for colors, 0x colors external dependencies in purple, and I think it looks good in Inferno too 🙂
