Fixed landscape bug. Sections can now be rendered in landscape mode.

[lowmanio]

The current version does not allow for landscape mode even though it is an option in the code. E.g.

section = Section(landscape=True)

This currently does nothing. I have fixed this so that the width and the height of the pages are switched over when landscape=True; thereby making the page landscape.

I have now added Unicode support
