Clippy UI has no accessible text

[claycompton]

1. Install the Inspect Object tool, which is part of the Windows 8 Software Development Kit
2. Navigate to a web page using Clippy per example and log in.
3. Go to https://qa.nugettest.org/account and click to show your API key.
4. Launch Inspect Object and, using the keyboard exclusively, tab to the Clippy button.

RESULT: The button has no accessible text of any kind. If you were using the screen reader NVDA, it would identify the button as "button button", which is bad.
EXPECTED: The Clippy app should expose accessible information, and it should mirror the text that's shown to sighted users. WebAIM has an overview of how to do this at http://webaim.org/techniques/flash/text.
