[CLI] Remove dependency on Ruby

[JoeStanton]

Resolves#275, #293. Discussed in #405.

Rewritten the init script in Node to remove the dependency on Ruby. I've also moved it into the react-native-cli directory as I thought it was cleaner.

Sweet!

init.sh should be outside of the cli folder. Since the cli is global, it's super hard to update. What it does is just forward all the commands to react-native which can be updated easily.

[JoeStanton]

Ah that makes sense, global packages are annoying to update. Moved it back out.

[vjeux]

Looks good, i'll test it and merge it later today or tomorrow, thanks!

This file no longer has to be invoked via shell. Since it's all JS, you can just require and run it from cli.js

[frantic]

Awesome job @JoeStanton! I have a few suggestions - see inline comments

Not 100% on this, but from when I started this over the weekend as well, I think that ruby’s __FILE__ returns just the filename (init.sh), while node’s __filename includes the full path resolution (/Users/user/path/to/react-native/init.sh).

@frantic what happened to this? Can we resurrect it?

[JoeStanton]

Hey! My fault - Life got in the way for a few weeks. I can finish this up in the next couple of days if there's still the appetite for it?

[nicklockwood]

@JoeStanton yes please!

[JoeStanton]

Hey Guys - Finally had a little bit of time, can you take a look at this? AFAIK I can't put init.js inside the local-cli folder as @vjeux said previously. Does this still apply?

Secondly, the init.js could be cleaned up nicely with some ES6 features, but I've targeted ES5 for the moment unless theres a way to run it through the packager (probably overkill).

[vjeux]

@JoeStanton you can't put it in react-native-cli, but you CAN put it in local-cli (that's the right place where to put it)

[JoeStanton]

Excellent - fixed that up.

[vjeux]

nit: space after if

[vjeux]

Thanks, a few minor details and we're good to go :)

[vjeux]

Oh you are right, nevermind me
