Implement wizards for RNA->cDNA processing

[Nicklas Nordborg]

This ticket is the master ticket for the multiple wizards that are needed to process RNA into cDNA which is about half-way in the library preparation process. We have identified about five sub-steps/wizards that are needed (subtickets will be created later):

1. Select RNA items and place on a plate. Sub-items and sub-plates are created without creation date to indicate that the laboratory process has not yet been completed. (#424)
2. Generate a lab protocol with necessary information such as storage location, etc. (#425)
3. Generate files that are needed by laboratory instruments so that users don't have to type or copy information manually.
4. Import quality control measurements.
5. Register the cDNA process as completed, including information about dates, operators, protocols, etc.
