V 2.2.5

I (Martin Hecht) have included the fix in 2.2.5, together with a few
more improvements:
- I liked the box which increased its size depending on the content. In
addition to the small and large box I have re-added this, and those who
like it as well can select this behavior by choosing the "automatic"
mode, now
- re-added error handling in the install procedure
- long lines without spaces still did not wrap around and caused the
with of the whole page to increase
