Tooling & fixing code style issues

[JuhQ]

• Added gulp
• Added eslint with airbnb config
• Added uglify
• Added package.json
• Fixed errors which came up with eslint

Note, even though I went through the file, fixed all the issues which came up in eslint and added gulp with uglifier, I did not test the code itself. But there shouldn't be any problems.

Hi there, can you resolve the conflicts please. Thanks. Also, it would be great if we don't change the code pattern.

[JuhQ]

Well, the only reason I did any changes to the code pattern was because eslint gave me 198 errors, all of which are now fixed in this PR..

Will resolve conflicts tonight.

It would be great if this lib had tests, so we could be 100% sure we don't break existing functionality by accident.

@JuhQ Sure thats coming soon, I'll be working on that by this weekend. Also, I appreciate your efforts, but just because we don't have tests for the same, I am bit reluctant for the lib pattern changes.

[JuhQ]

Totally understood. Let's merge this after there's tests, so I we can be sure this pr doesn't break any existing functionality. I'll rebase and refactor once some tests are implemented. Drop a note on this pr when they are done and I'll start work on that.

There's no reason to hurry this pr, better be sure no existing functionality is broken

@JuhQ Great, thanks a lot. I'll update you, once am done with the tests.
