Change slider label to indicate that there are no more steps to carry out.
Also indicate in the cover when no more steps are to be carried out.
Since we now know when the factorization is completed, let's not allow increasing the step count through the cover after that.
Update new and changed strings to existing translations.
Increase version number to 0.3.
Update translation binary files as well.
Word wrapping doesn't actually work unless the width property is set too.
When deducing whether factorization is completed, handle the special case of '1', which is not a prime, but not further factorizable either.
Add some full stops to user-visible strings and update respective translations.
Add German translation.
To get proper margins on both sides of the cover, obviously two times the padding must be subtracted from the width.
