fdo#69462 Properly escape URL in Mozilla -remote openURL(...) command

Verbatim ")" or "," in the URL will apparently cause problems when Mozilla-
derived browsers parse the openURL(...) command (see
<http://www-archive.mozilla.org/unix/remote.html> "remote control of unix
mozilla"), so percent-escape all "(", ")", and "," in the URL.  Also, remove the
space before "new-window" as "Commands should /not/ have spaces in them" (see
link above).
