Delete to recycling bin? about gdu

Thought: Your disk layout is as follows

$ df -h /root
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3        5G   2G   3G  60% /root

and you go ahead and as root delete a postgres database with 20GB from /var/lib/postgresql/.
This will fill up your /root/ partition to 100%. This needs to be taken into account when offering a feature like this.

What is needed to be done:

• create new enum DeleteAction of type uint8 which will consist of items: ActionDelete, ActionEmpty and ActionMoveToTrash in package tui
• modify handleDelete, confirmDeletion and deleteSelected to accept DeleteAction instead of boolean shouldEmpty
• add new key-binding D (big letter d) to tui/keys.go which will call ui.handleDelete(ActionMoveToTrash)
• add function MoveItemToTrash to pkg/analyze/file.go:
  • this function should create trash item according to the trash spec, so create a text file in info (e.g. ~/.local/share/Trash/info) and move the item into files.
  • it should respect the setting of XDG_DATA_HOME env variable
• add the new key-binding to help
• cover all the functionality by tests (every line, that could be tested, should be tested)
