Affinity v3 Initial Support

With the release of v3, there has been some changes:

• Packages {wine,wineboot,wineserver,winetricks} have been removed. There are instructions in the README.md to access these binaries.
• Packages {update,direct}* have been removed. There are instructions in the README.md to update the apps.
• Since v3 was unified into a single application, {photo,designer,publisher} remain the way to access v2 affinity, with v3 becoming the package to access the v3 application.
• Additionally, the default package now points to v3.

Please leave a comment in #69 if any v3 specific problems are found.
