Indentation issue in Day 9

[jasperhabicht]

The pseudo-code example for Nested Conditions in Day 9 has an indentation issue. Although this can't be compiled as it is no proper python, it should adhere to corect indentation. So, instead of

# syntax
if condition:
    code
    if condition:
    code

it should read

# syntax
if condition:
    code
    if condition:
        code
