- convert Textfiles into packed CR-format and vice versa
- convert Sprites into CR-format (optionally packed) and vice versa

!Scrap (!Temp) directory has to be set. Ticking the 'LZW'-entry in
the iconbar-menu enables data to be stored packed.

Sprites:
- x,y-resolution of sprites must be divisible by 8
- When converting graphics into CR format please ensure correct x:y
  proportions, e.g. x:y = 2:1. For example a mode 13 320x256 picture
  should be converted into 320x128 or 640x256 or the like...

Text:
- If the filesize of a packed textfile is bigger than its original size
  it is stored unpacked.
