With this change we get rid of the confusing key component checkboxes.
Now a component is either there or not (if left empty). There is
no redundant distinction between "unset" and "emtpy" anymore.
For compatibility with older databases that have "empty" passwords,
KeePassXC will ask if the user wants to retry with an empty password
if unlocking failed and the password field was left blank.
Besides these functional changes, the widget's layout has been
rearranged to be more compact, less stretched out (e.g. input fields
do not fill the full window width anymore), and more user-friendly
by providing a help tooltip for the hardware key field and accessible
descriptions for screen readers.
* Support importing 1Password vaults (.opvault folders) into KDBX database
* Entry attributes are filled based on section and field name
* Expiration dates are set for entries
* Entry URL's are set from a wider array of fields
