py-mako: updated to 1.0.9

1.0.9:
Further corrected the previous fix for 287 as it relied upon an attribute that \ 
is monkeypatched by Python’s ast module for some reason, which fails if ast \ 
hasn’t been imported; the correct attribute Constant.value is now used. Also \ 
note the issue was mis-numbered in the previous changelog note.
