Implement "Autofill form data" import for Firefox
This patches adds support to import autofill form data
from Firefox. Firefox stores form data in formhistory.sqlite
file and currently Chrome's firefox importer doesn't import data
from it.
With this patch, "Autofill form data" option is available in import
menu and allows user to import form data from Firefox. The imported
form data is stored in autofill table and is then used in forms for
autocomplete.
