Veib should have a password manager to auto-fill password fields

Steps to reproduce:

1. Go to a site with a login field
2. Enter your username and password
3. Click submit/save/login

Expected behavior:
Veib should prompt you to save your login information (and allow you to still do this if you dismiss the dialog). Upon subsequent visits to the site it should auto-fill the fields.

It should be possible to manage the passwords (view, edit, modify, delete)

It would be nice if the passwords were secured behind a master password, unlocked on browser start
