[Grml] Grml download size

Hi,

at first thanks for the good work. in my oppinion you offer the best linux live cd. but i have one thing to inprove:

at your download site is written that the multiarch download size is 700MB. But infact that are 731MB to download. normaly its ok to round such sizes but at this point it isnt. im sure you know why :)

so please correct this

greetings and keep up the good work
