[Initng] ng-update color fix

[Davide Barbato]

Hi people,
I had some error about ng-update colors: I got the color code instead of 
colored echos, like this:
 
~# ng-update add daemon/hotkeys
Warning:\033[00m "daemon/hotkeys" already installed in runlevel "default"

Well, it's simply an "-e" flag missing on echo.
To fix it simply add "-e" to every echo command into ng-update.
Another thing: the Warning() echo use a YELLOW color that isn't declared.
I'm using CYAN now, but isn't the same thing.
Hope this help :)
