Bug fix for capture target part III

Capture sequence queue files having targets set create problems when used with the scheduler, since they currently overwrite the target of the scheduled job and therefore create problems with capture counting.

This change creates the option for loading sequence queues and ignoring targets. This option is disabled by default but used when the scheduler invokes capturing.

Additionally, the meanwhile superfluous attribute m_RawPrefix has been removed from Capture since name sanitation is no longer necessary in Capture.
