[aprssig] APRS<=>E-mail

Different absolute upper limits depending on if the system detects the 
client as APRS-IS connected (TCPIP) or RF-connected (gated)?  
User-configurable if they want it to be lower than that absolute upper 
limit?

To throw out numbers, I'd say 1K for non-RF users, and 128 (or something 
thereabouts) for RF-connected recipients.  Remember that I'm proposing 
that those D7 (to pick on one small-screen device, nothing against 
Kenwood) users out there can set their limit MUCH less than the absolute 
maximum.
