This doesn't look right. Clicking the taskbar app launcher shortcut should still
show the desktop mode app launcher. Otherwise, if Chrome is in Ash mode a user
might not see the app launcher at all, since it pops up in Metro mode (or, e.g.,
a minimized window).

Note: launching Browser windows from it there should switch into Metro mode on
Windows 8. (On Windows 7 it should probably activate the Ash window, but I'm not
sure there's code to do that yet).

Creating a desktop environment breaks IME support as this triggers the input
method creation which is a singleton.

Bringing up the Ash service conditionally is probably OK (pretty sure it will
only get asked for when that flag is present). However, the desktop ServiceWin
should be unconditional (i.e. no `else`).
