Implement missing fbwhiptail features, minimally input, maybe multi selection

Fbwhiptail was made in a night. It's now used everywhere under Heads, well mostly. 


I'm working at color coding heads right now, and reducing noise and console input/output. 


To go further, input for text is missing from whiptail (modules/newt) into fbwhiptail (modules/fbwhiptail) 

Mutiselection to act as a configuration management as well would be nice to have.

Let's see what can be done?
