[ICONS] tool to create icons from svg

[Hervÿffffe9 Chanal]

The exported size are 16 22 24 32 48
It is based on the font_convert.sh file and the Frank Richter file
It use :
- The inkscape png export (because convert gives awfull results)
- Image Magick to decrease the color depth
- Icotool to generate the windows icons

Comments are welcome !
