Refactoring of modals (#294)

* Refactored modals (added CommonModal and DeletionModal besides ErrorModal)

This change allows more code reusage by defining a common modal that has a translated title with an optional icon.

* Replace the eslint-hack with a proper TypeScript conform solution

Instead of asserting non-null and disabling eslint, the 'as ...'-syntax is used to convince the compiler that everything is fine.

* Improved property names and ShowIf-construct

* Fixed missing renamings
