jsondatetime fails parsing lists

[kaleko]

If the json file being read in has a list of non-datetime values, for example
"mykey" : [ 123, 456 ],

the parser will fail with
AttributeError: 'int' object has no attribute 'items'

This comes from the iteritems(source) function. I was able to fix it with:
for k, v in source.items():
if isinstance(v, list):
#Note this probably will fail for a list of datetimes, but as of now that is not used
pass

but this will probably fail for a list of datetime objects. I haven't figured out how to solve it more generally for lists of ints and for lists of datetime objects.

Maybe a test could be added for the simplest case where the JSON is just a list:

>>> import jsondatetime as json
>>> json.loads("[]")
AttributeError: 'list' object has no attribute 'items'
