Implemented random colors and added back the playgrounds

This commit adds back the playgrounds and the npm demo. We also implemented a few
methods to generate pretty random colors.

Changes
=======
- Added back the playgrounds and the npm demos
- Implemented a few random color generators

rename makeNode back to create

- svg.js: The esm bundle
- svg.min.js: The bundle for all browsers for maximum support
- svg.node.js: The bundle for node
- polyfill.js: Using svg.min.js requires this polyfill in case the Browser does not understand all of ./config/polyfillList.js
- polyfillIE.js: This is required when you use IE11 (polyfill.js still required)

Please note, that not all test pass for IE11 due to its rounding issues and wrong calculation of bbox.
Also note, that `defaultPrevented` is not working for CustomEvents in IE11.

- Make sure _d is always defined
- Clean up object before init
- Check space in array
- Use passed space instead of space in object if available

- _d is initialized to 0 so toArray does not give you undefined
- fix tests

We now have tested and working color spaces, isn't that nice!

Changes
=======
- All color spaces are working

This commit reverts some of the rules we added on the linter, it changed a lot of
code again... but these won't happen too often.

Changes
=======
- Modified the linter again

This commit updates the color modules, so that the old tests pass, we just need to
modify the tests to test some of the new functionality (Since there was a lot of
copy and paste work done haha)

Changes
=======
- Updated the color module to support a number of color spaces
- Made sure all of the old tests are working again

This commit modifies some of the eslint rules, to allow our code to be a little bit more
readable. This came about because we had a particularly pesky problem, where the code
was indenting ternary operators. This fixes that, and makes it easy to add new rules
to eslint as we please in the future.

Changes
=======
- Rebuilt the library with new eslint rules
- Changed the eslintrc file to a yaml file by default

- words() and element() added to Dom
- svg() now returns the _parent_ of the imported element, when outerHTML is true (which means an element gets replaces)

- refactor code into functions
- handle timeSource correctly
- allow for immediate updates
- Runners dont know about their delay anymore. Thats far more simple.
- Timeline is paused on creation
