Summary
-------

This branches gets the Activator working 100% in IE7&8, Webkit, and Opera.

Implementation details
----------------------

Added disableTabIndex() function.

    examples/lazr/index.html
    src-js/lazrjs/activator/activator.js
    src-js/lazrjs/inlineedit/editor.js

Fixed all lint errors after discovering that some
of them were breaking IE, because this file becomes
part of the one big consolidated javascript file.
    src-js/lazrjs/testing/testing.js

Fixed tests to run in IE7&8, Webkit, and Opera.
    src-js/lazrjs/activator/tests/activator.js

Updated the tests for the new behavior of disableTabIndex().
This still does not pass all the tests in IE or Opera.
