Homing order in configtool.

Adjustments by Traumflug:

 - Rebased to current 'experimental'.

 - Some whitespace adjustments.

 - Renamed labelWidth_homing to labelWidthHoming.

 - Fixed an issue in printer.py which would write only the first
   character of an option ('x' instead of 'x_positive', 'n'
   instead of 'none', etc.)

Thank you very much for the code, Matt!
