Mac and Linux changes have landed. Windows was complicated by the fact that we need to write to the 64-bit registry from our 32-bit installer, and is still in progress.

Install Firefox native messaging reg keys on Windows

While Chrome checks both the 32- and 64-bit registries to discover
native messaging hosts, Firefox only checks the native registry. This
poses a challenge, as 32-bit installers generally aren't allowed to
install 64-bit components (such as registry keys). However, it turns out
that it is possible to suppress the resulting error, and this CL does
just that, allowing the required keys to be installed in the native
registry on 64-bit Windows.
