2.1.1: Merge pull request #4 from MidnightBSD/upgrade_migration
Provides the following enhancements:
- export and import commands. These are experimental. import has a few bugs that limit it's usefulness at the moment. Even still, export will create a file of all the installed packages. This can allow you to script installing packages on another system or restoring after a major update.
- Migrating several mport specific functions into libmport so that they can be used from the graphical package manager or other apps.
- Fixes a bug with update introduced in the last release.
