Packages.json needs to contain all the used packages

[omardiaa]

The following packages were not installed when I tried to install ethereumjs-wallet into my project:

• stream
• assert
• buffer
• crypto

Suggested change:
Add the following to packages.json inside dependencies:
"dependencies": {
"assert": "^2.0.0",
"buffer": "^6.0.3",
"crypto": "^1.0.1",
"stream": "^0.0.2"
}

Are you using this in browser? Those look like polyfills for NodeJS builtin modules used by this library and we wouldn't include those in our package.json since this library doesn't currently provide a browser-specific build (though not to say we can't explore that).
