Still using old-style class definitions.

[nicerobot]

The old-style classes are used throughout TileStache. e.g.

class Layer:

Better:

class Layer(object):

Try (step 1):

find . -name '*.py' | xargs perl -pi -e 's/((^|[ ])class [^ (:]+?):/$1(object):/'

My minimal testing so far shows no issues with this change by i haven't run any thorough test suite to compare before and after.
