Request for review: Shotwell Mallard documentation

[Robert Ancell <robert ancell canonical com>]

Hi,

I've taken the documentation from the Shotwell website [1] and made it 
into a draft Mallard [2] document (i.e. offline documentation).

To download the document and view in Yelp try the following commands:
$ bzr clone lp:~robert-ancell/+junk/shotwell-help
$ yelp shotwell-help

Please review/comment.

- Not sure of the license on the Shotwell website, can I use the content 
in the document and under what license?
- I think it needs some images
- Any major sections missing?  I've tried to be conservative on the 
amount of information provided
