Description

Many settings in the Cas Editor need to be saved in a type system scope. This is for example the configuration of annotation styling, annotation key bindings, etc.
Plugins which extend the Cas Editor have the same requirement, but the Cas Editor does not support writing of preferences to the existing DotCorpus file, which is saving preferences per type system.

To fix this replace the existing DotCorpus file with an eclipse preference store. This preference stoer can then also be used by plugins to save type system scoped settings.

Existing DotCorpus files must be migrated to the preference store. This should be done in a similar way as the migration of Cas Editor projects is done. A popup dialog ask the user if he wants to migrate.
