[ECOS] Config tool 2 progress indication

[harri.siirtola@vtt.fi]

Another annoying thing is, the bottom window scrolling doesn't work for me.
It fills to some extent, then starts jumping back and forth between the end
and middle of the contents. No big deal, but makes it impossible to follow
the progress (having learnt to see the build stage from the filenames being
compiled). Is it just me?
Thanks,
