KeeDoc v0.5.0

Added

• A value copied from a card no longer stays on the clipboard. It is cleared
  30 seconds after copying, and at once when the vault locks, so another app
  cannot read it later. The message shown after copying says so. Anything
  copied elsewhere in the meantime is left untouched.
• Choosing a master password, when creating a vault or changing its password,
  now shows how strong it is: weak, acceptable or strong. It is only advice;
  the minimum of 8 characters is still the only requirement.
