Branch:

default

Phase:

public

Message:

Added support to delete up to N stamps from the list:

• Delete the last recorded stamp:

stamp -d 1

• Delete the last 10 stamps:

stamp -d 10

We ask for confirmation before proceeding with every stamp, in case
the user asks for the removal of multiple stamps, as soon as he does
not remove one of them, the following stamps could not be deleted.
