This commit solves a problem with the commandline interpretation of the "install_options". Command Line Arguments wich are given as hash are interpreted in the following way:

Option: [{'--from' => 'REPONAME'}]

Interpretation at the system: zypper in "--from 'REPONAME'" ....

The solution is simple:  "="

zypper in "--from='REPONAME'"
