Bug 27560 - Remove reference to "events" in the introduction

[mwatson2]

Bug 27560:

In the introduction:

"SubtleCrypto interface, which defines a common set of methods and events for dealing with initialization"

Not sure what "events" means in this context. Perhaps that wording comes from the version of the spec before Promises.

Other problems in this section:

(2) "and completing the operation to yield the final output"

--> Not the case anymore in Promise-based version of WebCrypto

(3) "the API provides interfaces for key generation, key derivation, key import and export, and key discovery."

--> Key discovery is not covered by this document, but is part of a separate spec. Should we link to that or remove this comment?

I suggest
(1)(2): "...SubtleCrypto interface, which defines a set of methods for performing common cryptographic operations."
(3) Remove key discovery from the list.
