Introduce the i3-sensible-{pager,editor,terminal} scripts
The former two provide fallbacks in case $PAGER or $EDITOR is not set (which might be more common than you think, because they have to be set in ~/.xsession, not in the shell configuration!) while the latter tries to launch a terminal emulator. The scripts are most prominently used in i3-nagbar, which alerts the user when the configuration is broken for some reason. Also, i3-sensible-terminal is used in the default configuration. This commit does not rely on the shell supporting ${PAGER:-less} anymore, which is not the case for 'fish'.
