Fixed the broken autocomplete

[JannoTjarks]

I fixed the autocomplete problem from this 3 issues:

45 #46 #47

I moved the color attributes direct into the prompt variable, away form the print command. Same approach like in all other functions.

@avalonwilliams please take a look.

Fixed bug: Current master branch: After my changes:
