[ngs] better prompt

[Istvan Albert]

if you want to preview what it does just paste it into the comman line,

once you add it to to your bashrc it will get applied every time you
open a new terminal

basically it is a nice colorful prompt that will display the computer
name with green and the folder names with orange, plus it moves the
cursor on a different line thus making the command lines easier to see
