cansniffer: add new interactive commands to enable/disable SFF/EFF frames 

With the new commands

a<ENTER>        - enable 'a'll SFF CAN-IDs to sniff
n<ENTER>        - enable 'n'one SFF CAN-IDs to sniff
A<ENTER>        - enable 'A'll EFF CAN-IDs to sniff
N<ENTER>        - enable 'N'one EFF CAN-IDs to sniff

the EFF/SFF frames can be added/removed with a single command.
Of course this could be done with the '+' and '-' filters too.
But 'N' is much easier to type then '-0000000000000000' ...
