Delete functionalities in all clients

[jburel]

Synchronize clients.

• make distinction between delete and remove.
• delete images, datasets, projects etc.
• delete annotations
• etc.

Some functionalities already in place in Insight. Need to be reviewed, probably use them as a starting point.

Delete status in insight

• Delete Image
  • Select the image from Tree view (left panel) or Browser view (central panel)
  • Right-click, and select the Delete Option.
  • Delete box pops up to confirm the delete action and to offer the option to delete the tags or attachments linked to the image. The other types of annotation that cannot be shared, will be removed automatically e.g. comments, ratings
• Delete Dataset
  • Select the dataset from Tree view (left panel)
  • Right-click, and select the Delete Option.
  • Delete box pops up to confirm the delete action and to offer the following options:
    • delete the images contained in the dataset.
    • delete the tags or attachments linked to the dataset. If the user decides to delete the images contained in the dataset, the same rule applies i.e. annotation linked will/won't be deleted
• Delete Project
  • Select the project from Tree view (left panel)
  • Right-click, and select the Delete Option.
  • Delete box pops up to confirm the delete action and to offer the following options:
    • delete the datasets (and images contained in them) contained in the project.
    • delete the tags or attachments linked to the project. If the user decides to delete the datasets contained in the project, the same rule applies
• Delete Plate
  • see Delete Dataset
• Delete Screen (not available)
  • see Delete Project

Important:
The option to delete "tag, term or attachment" while deleting an object (e.g. image) will be OFF by default.
