Hi, thanks for your contribution.

The problem with your implementation is that packages now will appear multiple times if the user has multiple computers due to your foreach($myComputers as $computer) loop. Can you please fix this? Please note that multiple operating systems are allowed too (comma separated) and the OS version should be checked too. If the os and os_version of the package is empty, the package should be treat as compatible for all platforms. You can use the already existing functions isOsCompatible() and isOsVersionCompatible() for that.

I'm not a fan of overwriting $forceInstallSameVersion in the deploySelfService() function. Instead, I'd like to make this configurable similar to the job priority, see here.

Please also use tabs instead of spaces for indentation.
