[PD] Abstraction arguments: tell apart symbols from floats from no argument at all

[João Pais]

another way to do it might be the following. I don't have now the time to  
test it:

- loadbang a list with all the arguments (maybe initiated by something  
like [list $1 $2 $3 ... $16 or whatever])
- use an abstraction from list-abs to drip the list
- send the output through a route to test the type

If you know beforehand that 0s won't be part of the arguments, it will be  
even easier, just filter out the 0s when detecting the argument type.
