Release 12.0.0

[voxpelli]

As ESLint 5.0.0 is now released it would be neat to get eslint-config-standard 12.0.0 released as well.

Some stuff should probably be done first though:

Required:

• Change peerDependency to require the stable version
• (anything else?)

Nice to have:

• Merge Update eslint-plugin-node to the latest version 🚀 #108 – moves to newer eslint-plugin-node
• Merge Update eslint-plugin-node to the latest version 🚀 #126 – moves to even newer eslint-plugin-node
• Merge Update eslint-plugin-promise to the latest version 🚀 #128 – moves to latest eslint-plugin-promise
• Maybe merge Add the object-curly-spacing rule #124 (see Release 12.0.0 #123 (comment))
• (anything else?)

Does the PR consider also this issue when using eslint 5?

(node:12988) [ESLINT_LEGACY_OBJECT_REST_SPREAD] DeprecationWarning: The 'parserOptions.ecmaFeatures.experimentalObjectRestSpread' option is deprecated. Use 'parserOptions.ecmaVersion' instead. (found in "standard")

Would be great to get in #124 as well

@StarpTech @yuchonghua That should already be fixed in the alpha release of this module, see #117 and 6a89a51, please try that one

[voxpelli]

@LinusU Added that to the list, is a review by @feross or such needed for that to be merged?

[yuchonghua]

When will it be released?

I guess that #126 should be merged as well before 12.0.0 is released, so that the module is as up to date as possible

It seems that all the upgrades with eslint5 are stuck here. Can it be solved as soon as possible? It doesn't have to be solved in the 12.0.0 release, you can solve it at 11.0.0+ first.
