views: Hook the view_in_browser functionality with its key.

This commit hooks the view_in_browser functionality with the key
for it. Any message can now be viewed in the browser by pressing the
view_in_browser key from the MessageInfo view. It also adds tests
for the corresponding keypress in test_popups.

Test amended.
