[vte] vte.sh: Add vte.csh, a tcsh counterpart of vte.sh

[Christian Persch <chpe src gnome org>]

commit 3bd204b9400650ff75197b4a1ab65711a58b5388
Author: Carlos Santos <casantos redhat com>

    vte.sh: Add vte.csh, a tcsh counterpart of vte.sh
    
    Use vte-urlencode-cwd in the precmd alias. This overrides an existing precmd
    and can also be overriten, like happens with the PROMPT_COMMAND variable
    in vte.sh.
