Web Updater: forced linebreaks at "Downloading" and "Updating"

[mmattel]

Optical things:
Note, browser is close to full screen...

When you do an update over the webinterface

you get at the point of Downloading.
It does not kook good that the line gets split at the downloaded point, see below.

Suggestion: make either one line or make a new line for downloaded (preferred) but do not break in between. If fixed with a new line at downloaded, it would be great to have the % sign as close as possible underneath

At Updating: "only a limited number of commands" and other lines

@mmattel Right now web interface uses CLI output with a simple purification.
