Make delete, rename and move undoable

Browse Source 
A delete is no longer a removal: it is a move into a hidden .plainfiles-trash folder on the same volume, which costs a rename and keeps the item recoverable. The snackbar offers Undo for delete, rename and a pasted cut; the handle is cleared as soon as it is used.

domain/Trash carries four deliberate limits: the trash lives on the users own volume, so it counts against their free space until it expires (24 hours, purged opportunistically, no startup hook and no empty-trash chore); a name taken again in the meantime is never overwritten, so an item returns beside it; a delete through Androids own dialog is not staged because the system owns it; and each item is staged in its own slot so two files sharing a name cannot overwrite each other on the way in. When a pasted move landing names cannot be established with confidence, no undo is offered rather than risking the wrong file moving back.
