In place text editors

In place text editors should be used where possible.

The following places are a minimum:

• Adapter general settings (name, comment, object class, base connector)
• Connector general settings (name, comment, queue when blocked)

Should probably be done using extension methods that are also available to connector developers so that they can have in place editors as part of the display template. May impact IDB-960. Think about user permissions also, but that may have to be extended when the "security enhancements" road map item is done.

This will also solve PRODUCT-261.
