Provide more information on processors

[EEngl52]

When refering to kwalitee as an information source on how to use the OCR-D-software, it would be helpful to include to following pieces of information:

• level of operation: if the level of operation a processor works on could be filtered, you could see at a glance which processors can be used for which steps in the workflow
• input and output-filegroup: especially for defining workflows with ocrd process or Taverna it would be useful to know how many and which input-filegroups are expected and which output-filegroups are produced

Furthermore, the link from the processors to the readme of the projects is a bit confusing as it just leads you to the general kwalitee project website where you still have to search the particular readme you are interested in. It would be way clearer if the link led you e.g. to the expanded project information.
