"make compile" throws some errors about missing modules

[kalikaneko]

I'm getting some errors while compiling the web-ui.

 ERROR in ./app/js/index.js
    Module build failed: Error: Cannot find module 'escape-string-regexp'

It also was missing 'ms', 'strip-ansi', 'has-ansi', 'supports-color', and 'ansi-styles'. I installed them with npm install, and the make compile finished without errors (only some warnings).

@kalikaneko
It seems pixelated-user-agent/web-ui/Makefile is very outdated.
We've been using pixelated-user-agent/Makefile for a while now.

Do you think you need a specific Makefile for web-ui or we can drop it?
