Removed require() node specific function call.

[pricop]

Sorry for bundling all the fixes at once but I don't have enough time to break everything apart:

This pull request fixes the following:

---

For issue: #167

• Fixed require() node function call completely breaking the ES6/UMD bundle

---

For issue: #165 and #169

• Fixed the country highlight is no longer removed once the mouse has left the country's boundaries, essentially letting the "active" border around it on Windows devices (see video).
• Fixed the country tooltip is "stuck" on the edge if the mouse goes outside the boundary of a country, but doesn't land on another target on Windows devices (see video).
• Fixed the href URLs applied to each dataset is not opening on Windows devices (not working at all).

Here's a video demonstrating that it works as it should now (you can compare it with the video from the issue: issue):

For issue: #170

• Fixed datasets with URLs instantly opening on mobile devices (very bad UX, the user cannot see the tooltip information before being sent away from the page)
• Fixed datasets with URLs not opening at all on Windows devices
• Improved the UX on mobile devices: On touch (tap), we first show the tooltip, and ONLY on a subsequent tap we nagivate the user away. This is the expected UX on all major chart libraries.
• Improved the UX on mobile devices: when dragging out of a country boundaries onto unused (ocean) space, the tooltip fades away

With these changes, we're moving away from the mouse events in favor of pointer events, with fewer overlapping events that could conflict with eachother.

As a bonus, since switching to pointer based events, support for pen devices such as Apple Stylus and basically any other pen (but not only) pointing device is greatly improved.
