mark strings extracted from PyArg_Parse* as "const"

- Various places within the bindings use PyArg_ParseTuple[AndKeywords] to
  extract (char*) string arguments. These are pointers to the internal
  representation of a PyStringObject, and shouldn't be modified, hence
  it's safest to explicitly mark these values as (const char*), rather
  than just (char*).
