Update jscs to version 3.0.0 🚀

Hello :wave:

:rocket::rocket::rocket:

jscs just published its new version 3.0.0, which is not covered by your current version range.

If this pull request passes your tests you can publish your software with the latest version of jscs – otherwise use this branch to work on adaptions and fixes.

Happy fixing and merging :palm_tree:

GitHub Release

Version 3.0.0 (2016-04-14):

Hell yeah! 3.0 is here. First and foremost we rewrote every... single... rule. We fixed a plentiful amount of bugs (most of which were found during refactoring those rules using CST). This provides us the opportunity to include autofix for complicated rules like the brand new disallowUnusedVariables rule (see below).

Breaking Changes

If you aren't a plugin writer or support build extensions (like grunt or gulp), etc you don't have to worry about anything.

We didn't rename any of the rules or remove any of the deprecated rule values; it is all still there. All you have to do to update is just bump the jscs version in your package version to 3.0.0 and be done with it.

One thing to notice though: the yandex preset was removed. Since Yandex doesn't have official code style (don't look at the https://github.com/ymaps/codestyle), we were requested to remove it

One drawback from all these changes is that JSCS might be a little, just a little slower, so if you find any issues related to that - don't hesitate to drop us a line, or just drop us a line we are all friendly :).

New rules

Since this release is about rewrite of internal design, we adding only four new rules (all of them were added by our contributors!).

`disallowUnusedVariables` by Brian Schemp

That rule useful when you have var x = <whatever> and you don't export that x and don't use it. This rule will highlight that and remove it if you want.

`disallowSpacesInsideImportedObjectBraces` and `requireSpacesInsideImportedObjectBraces` by Maks Sadowsky

When you need or don't need additional parentheses -

import /*–>*/{foo, bar}/*<–*/ from 'foo-bar';

`requireUseStrict` Erik Vold

Short and cool - ask you to use "use strict" pragma on top of the file if you so desire.

`requireImportsAlphabetized` by Ray Hammond

Keeps your imports alphabetized, pretty handy way to keep your dependency in tidy state.

The new version differs by 213 commits (ahead by 213, behind by 37).
