better check of verb conditions, sequences not allowed on SA

The execution of a verb can have many different side effects
affecting the execution of a following one: a verb can (un)stage,
change files, change their types, change the focused panel, etc.

It's too hard to reason about all those effects, and this can't
be expected from the user. So, at least for now, I forbid sequence
execution on multiple files.
