Image Component Library

The new version comes up with the following major changes:

• Full integration of Carsten Schürmanns Myrmex tactile device
  (simply use icl-camviewer -input myr 0 to grab images)
• new embedded GUI component 'color' that can be used to conveniently
  choose a color at runtime
• new lookup-table function 'lut' was directly integrated into the Img<T>
  template class
• new PseudoColorConverter class was added to the ICLCC package

Further fixed:

• fixed overlayed rendering of rectangles
  (these were shifted by dx=dy=0.5 pixels before)
• fixed some documentation issues
• fixed problem with icl-create-project script in particular, when the script
  is called with the --update option
• further minor fixes
