As a user I want to save my created computation template to the platform I am on

[aseeland]

When creating a computation template inside DaRUS or Ilias the frontend should provide the possibility to save the file directly to the platform (DaRUS dataset or Ilias test) the frontend was called from, and not only to the local disk of the user.

Requirements: user needs to be logged in to the platform.

Could be implemented as a REST call to the parent frame ( DaRUS-connector / Ilias-Plugin(?) ).
