Subject: refactor!: don't show autotype when action is copy

this changes the default behavior of the 2nd menu. if copy mode is
selected, it doesn't make sense to show the user the option to autotype
the username and the password. the option for autotyping has been
removed if copy mode is selected.

the autotype, both, and the default action mode have the same contents
in the 2nd menu. however, the default mode has a third menu which asks
for a user action.

the chosen_key variable was made a global variable rather than a
dynamically scoped variable to avoid confusion. i must admit,
dynamically scoped variables sounds kinda insane when you realize that
scripting languages like Lua support lexical scoping.
