[sugar] free disc space in journal

[Christoph Derndorfer]

Hey,

I just ran into ticket #6354 ("Record activity -- how full is too full?" 
at https://dev.laptop.org/ticket/6354) on my XO and now I was wondering 
whether there are any plans to integrate a way of letting the users know 
how much disc space is still available into the Journal. Using MB values 
probably doesn't make sense but some kind of colour-coding system could 
be used...

I'm thinking this is also an interesting issue wrt cjb's "Disconnected 
backups" project.

Greetings from Vienna,
Christoph
