Subject: Add support for the BROWSER environment variable

Allow user-defined URL-opening commands via the BROWSER environment
variable. This enables using a non-default browser, or changing the
browser for a single command.

For example, on Mac:

    $ export BROWSER='open -a Firefox'

Windows:

    > setx BROWSER "start iexplore"

In UNIX environments, the command is run through `$SHELL -c`, or
`/bin/sh` if `$SHELL` is not set. On Windows, it uses `cmd /c`.

Ensure that URLs are properly quoted between UNIX and Windows
environments in `fmtBrowserCmd()`.
