/**
   Manages installing of extensions in the GUI mode. Requests for installing
   Extensions can be asynchronous. For example, the Extension Manager is running
   in an office process and someone uses the system integration to install an Extension.
   That is, the user double clicks an extension symbol in a file browser, which then
   causes an invocation of "unopkg gui ext". When at that time the Extension Manager
   already performs a task, triggered by the user (for example, add, update, disable,
   enable) then adding of the extension will be postponed until the user has finished
   the task.

   This class also ensures that the extensions are not installed in the main thread.
   Doing so would cause a deadlock because of the progress bar which needs to be constantly
   updated.
