Zypper/One Click Install pin repo to package.

I have this problem:
When installing software not included in default repo by OCI, I uncheck keep repositories after install option. That causes some problems. Solution may be pinning repo to package (OCI will display checkbox for that). In this case, pinned repo is only used in process of updating this package. Another solution is to set pinned repo to lowest priority.

What problem is addressed by this ideas:
1. If I disable repo, there's problem with update system
2. If I don't disable repo, system could been broke in future
