Update examples to 1.4.0

[diarmidmackenzie]

This PR updates all examples to A-Frame 1.4.0, and fixes various issues arising:

• THREE.Math -> THREE.MathUtils
• Move from aframe-teleport-controls (old, unmaintained, broken in A-Frame 1.4.0) to blink-controls (maintained).
• A workaround for A-Frame issue 5203 (which looks like a regression in 1.4.0).
• Patch ammo-debug-drawer to addresses various THREE deprecations (would be nice to move to 1.0.1, but that uses ES6-style import/export, so needs PR Move builds from browserify to webpack #22

Of the issues found upgrading to 1.4.0, the ones that aren't fixed are:

• Infinite loop when applying impulse to shape #24, which I will handle as a separate PR.
• New error hit in Cannon Worker Driver ttl example (A-Frame 1.4.0) #25 which is specific to Cannon Worker Driver, and I don't plan on fixing.

Changes looks good, I added some comments. I just reviewed the changes in this PR, I didn't test the examples myself.
