tools (common/template): new `fallback` settings: `fallback` can be used to change fallback behaviour. By default, fallback is done on `default` theme, this can be set to an other theme with a string, or to a list of fallback. The list can also be empty is no fallback is desired (notably usefull for "main" themes, on which other themes may fallback). This setting replaces `css_default_fallback`.

#!/bin/sh

eval $(dbus-launch --sh-syntax)

# default, backend is launched in foreground
if [ $# -eq 0 ]
then
	exec sat fg
fi

# backend is launched with an explicit subcommand
if [ $1 = fg -o $1 = bg -o $1 = debug -o $1 = stop -o $1 = status ]
then
	exec sat "$@"
fi

# a whole command is specified
sat bg
exec "$@"
