Good news everyone !

Since the 0.9, main changes are:

Sales de Andrade)
- Documentation updated, completed and clarified
- TWAIN: Add support for frame options ('tl-x', 'tl-y', 'br-x', 'br-y')
- Sane: Fix support of backend 'net'
- Fix normalizer 'min_one_source'

From there, I'll be able to focus my work on Paperwork once again \o/.
The first order of business will be to make a new release of Paperwork.
This release will include Libinsane support, some GUI changes, and many
bug fixes that have accumulated over time.
