`ValueError: invalid interpolation syntax in '%' at position 0` if you have a password with % in it

[beaufour]

With snoo 0.3.1, a password with % in it throws a ValueError. It's easily reproducible on first run (with the absence of a config file I assume). Just enter any username and % as the password:

$ snoo status
SNOO Username: boo
Password:

Aaah, that's a problem with configparser, because % needs to be escaped in the config file (as %%)
