Hi,

When installing Steam from the *.deb package, I got this error:

 steam-launcher depends on xterm | gnome-terminal | konsole; however:
  Package xterm is not installed.
  Package gnome-terminal is not installed.
  Package konsole is not installed.

This error is expected as I use none of the above, but urxvt. It would be great to support it.
My executable is urxvt, but other people might use rxvt or rxvt-unicode.

Thank you.
