[vte/vte-next] bash: Add /etc/profile.d/vte.sh script

[Christian Persch <chpe src gnome org>]

commit 2aa265c5c597c3230a7af4261b07544fa62389bd
Author: Christian Persch <chpe gnome org>
Date:   Mon Jun 4 23:51:27 2012 +0200

    bash: Add /etc/profile.d/vte.sh script
    
    This script exports __vte_ps1 which when used in PS1 will keep the terminal
    updated about the current directory. Use like this in ~/.bashrc:
    
    export PS1='\[$(__vte_ps1)\]'$PS1
    
    The urlencoding code is taken from gnome-doc-tool.
