Corrected some Traceur results.

Traceur does not actually support these things:
 * Number() support for octal/binary
 * WeakMap/WeakSet deletion methods
 * BLFD
 * String HTML methods
 * RegExp#compile

It does, however, support some Symbol stuff (including Symbol.iterator).

Also fixed one EJS result.
Changed the browser feature tally to a percentage.

Added TypeScript column.

TS only supports a few things right now, but they're there. Note: TS fails all of the class tests because it doesn't allow classes declared anywhere other than module top-level.
Forgot to add skeleton.html.
