Help Menu: Refactor and move to general settings

[CFuerstenau]

Solution for now:

• Remove all manifest help URLs. Only set the link via general settings. It's up to the user how much and what he likes to see. Can add as many custom links as needed.

What is going wrong?

Help menu has many entries: documentation, search, ...

• all end at the same page: Documentation/General
• naming/order is different from the documentation
• do we still need visualization, data structure
• should FAQ be part of the documentation

How is it supposed to work?

• Clean up help, remove no longer available parts
• Rename and order the option to fit to the structure of the documentation
• redirect to the specific part of the documentation

How can it be reproduced?
