v2.0

Major refactoring with bc breaks has taken place. Therefore, this will be treated as a v2 release from now on. No stable v1 will be released.

• Replaced setters with factories in order to make it easier to generate valid and complete data group elements.
• Changed namespaces.
  Most important: Sprain\SwissQrBill\DataGroups is now Sprain\SwissQrBill\DataGroup\Element for data group content elements.
• Renamed interfaces and abstracts to more descriptive names, removed unneeded directories.
  Example QrCodeData is now called QrCodeableInterface.
• Added functionality to save qr codes as svg as well as png.

Have a look at doc/example.php to get a better sense of the changes.
