[Canola] Additional permission to the GPLv3

During the Canola presentation in the Mozilla/Maemo Danish Weekend event that is taking place at the IT University of Copenhagen, Eduardo Lima, also known as Etrunko, one of the maintainers and core developers of Canola, announced that the following statement will be added to the license: "The copyright holders grant you an additional permission under Section 7 of the GNU General Public License, version 3, exempting you from the requirement in Section 6 of the GNU General Public License, version 3, to accompany Corresponding Source with Installation Information for the Program or any work based on the Program. You are still required to comply with all other Section 6 requirements to provide Corresponding Source." As you know, section 7 of GPLv3 allows copyright holders to issue additional permissions and this specific additional permission is compliant with the said section 7. The language for this additional permission has been written according to the requirements of GPLv3. We believe this additional permission enables wider use of Canola2 in different kind of business models and product offerings, especially in CE devices. This additional permission combines the best parts of GPLv2 and GPLv3 experiences. We encourage other projects to consider use of this additional permission if they have similar needs. Code has been changed to comply with this license, and is is available at http://code.openbossa.org
