Package missing Conflicts: horde <= 3.0 in .spec that leads to unpredictable
results during upgrade.
Steps to Reproduce:
1. apt-get install horde (using Sisyphus from archive)
2. apt-get update (from current Sisyphus)
3. apt-get install horde -> crash!boom!bang! we have unworking horde installation.
seamless upgrade procedure from older horde (maybe trigger instead Conflicts
what just copy old configs to another dir and prints warning message).
Horde will be rename to HordeN. N is nubmer of version.
horde* and Horde* are currently missing in Sisyphus.
