bug#19921: Support URL open for upcomming Mozilla Firefox 36

[Ryo ONODERA]

Hi,

Firefox 36 or later has no "-remote" command line option anymore.
browse-url-firefox of Emacs uses this "-remote" option
to open URL as new window or new tab.
We should use "--new-tab URLString" or "--new-window URLString" instead.

See
https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options#-remote_remote_command
> This feature has been removed in Firefox 36.


Following patch uses --new-tab or --new-window command line option.
This works with Mozilla Firefox 36.0 build 10.
