Subject: [PATCH] Lib: Use items() when appropriate in dict iteration

When both key and value are needed,

    for key, value in dictionary.items():
        ...

is used instead of:

    for key in dictionary.keys():
        value = dictionary[key]
        ...

Thanks to Jon Dufresne for finding keys() usages.
