nit: mark as "explicit"

[Bryan Eyler, 2013/07/24 00:33:53]

Done.

[eroman, 2013/07/19 01:11:13]

nit: add the parameter names (blink style omits them, however chromium includes
them)

[Bryan Eyler, 2013/07/24 00:33:53]

Done.

+
+  virtual void abort() OVERRIDE;
+
+  virtual void finish(WebKit::WebCryptoOperationResult*) OVERRIDE;

Add the parameter name

[Bryan Eyler, 2013/07/24 00:33:53]

Removed param as part of new interface.
