Feature request to add text and image rotate

[chwo...@gmail.com]

I think we should add a feature to allow users to rotate text and
images. I have created a patch for r214 which adds the "rotate"
option to both the text and images. Please let me know what you
think. Should we go about this in a different way?

The file attached contains a sample image and patch to show what can
be done with the following presentation.

slide:
- text: 'Text 1'
- text: 'Text 2' x:25 y:25 rotate:90
- image: 'data/tutorial/tux.png' x:40 y:20 rotate:45

Apply the patch by placing it in the src directory and executing

"patch -p1 < xsw.rotate.patch"

Also, is it possible to add the uploading of files to the discussion
list? It would be much more convenient.
