Added some (naive) text wrapping in the schedule #3010

For it to work make sure you have word wrapping in ods.

It's still very naive since it's taking constant font width which could vary depending on font type, font size, font lettering. The proper way would be is to either find some svg way to do it (couldn't find any stable one) or to render text to identify it's width (could be done with PIL but seems overkill, atleast for now).
