Add left/right navigation to move between modules

[wapgear]

When we have more than 5 modules (depends on the name size) we can't select it with mouse anymore.
So I think we can use left/right keys to switch between modules.

@parkerziegler WDYT?

@parkerziegler -- I'm on board with this change and have kicked the tires. Any thoughts before I proceed?

[wapgear]

@ryan-roemer any updates? :-)
If need to change anything I could do it on weekend

[ryan-roemer]

@wapgear -- Thanks for checking in again! Can you catch this PR up to master and just kick the tires one last time with our example of yarn dev and make sure things work as expected...

Also, do you know how this deals with overflows (a la #268 Display overflows)? Would this PR fix that issue as well?

I think we may be able to close out #242 as well Unable to do pagination on the tabs when many chunk files are showing

Hopefully we can close out both of these issues with this PR!

[wapgear]

@ryan-roemer Not sure about #268 but definitely it solves the #242 issue

Will update with master tomorrow and will test it! Thanks

[wapgear]

@ryan-roemer I merged latest master changes and tested it - works just fine.
About issues #242 - yeah, this PR fix it
#268 - unfortunately (or maybe luckily) can't reproduce it on my projects

Released in webpack-dashboard@3.2.0

Thanks @wapgear ! 🎉
