[update] Installer 3.1.1
Der Installer hat Version 3.1.1 erreicht. Und da niemand ein vollständiges Changelog postet, findet ihr es hier.

- Localization support (.lproj all the way!)
- Sources fetched are no longer cached
- Fast respring for 1.1.3+
- Source description cell height is now dynamic as well.
- Single source refresh button in the source info.
- Experimental version comparison algo to prevent update offers when package is present in multiple repositories (only when version number can be decomposed using standard Apple’s algorithm).
- Search field for the Uninstall section.
- Adding a repository will only refresh it and not all of the sources.
- Fixed an issue with permissions for the folders being created not getting proper permissions.
- The section list table is now properly resized when keyboard appears/disappears.
