--- Create a new button to use as binding.
-- This function is useful to create several buttons from one, because it will use
-- the ignore_modifier variable to create more button with or without the ignored
-- modifiers activated.
-- For example if you want to ignore CapsLock in your buttonbinding (which is
-- ignored by default by this function), creating button binding with this function
-- will return 2 button objects: one with CapsLock on, and the other one with
-- CapsLock off.
-- @see button
-- @return A table with one or several button objects.
