getEventCharCode unit tests

Removed script security attributes, since fb.me isn't setting the proper headers.

…per headers.

[website] Fix jump on the header

Algolia adds two inline styles

```css
  position: relative;
  vertical-align: top;
```

to the element once the script inserted at the end of the page runs which super slightly moves the header. The fix is to always apply those two rules this way it doesn't jump. I did not notice it on my machine because it doesn't move when custom fonts are not being used.

Test Plan:
- Open two tabs: reactjs.com and localhost:4000/react
- Click around on reactjs.com to prime the cache with the fonts
- Switch tabs and click around on localhost (but do not force refresh!)
- Now you get custom fonts loaded locally and it doesn't jump when you change tabs

Use loose-envify instead of envify

This reduces the number of transitive dependencies and decreases the build time (by ~6% on my machine).

Free memory allocated by testElement after usage

IE11 reports `testElement` as detached DOM node consuming memory. It is captured in closure of `setInnerHTML` function and could be safely cleared after feature test.

Adds unit tests to getEventCharCode.

Remove unused export from DOMChildrenOperations

Strip complex values from ReactPerf.printDOM() output

We suspect that memory overhead caused by coverage might be the reason Travis fails on master. No guarantees it will work but worth a try.

Fixes #6288

Rename ReactPerf methods to match the upcoming ReactPerf revamp

Remove react/addons

Make ReactPerf.getLastMeasurements() opaque

We intend to change the measurement format significantly in #6046. In order to introduce the new ReactPerf during 15.x release cycle, we are making the measurement structure opaque-ish in 15.0.
