Michael Thon 80ffb169c1 [Python] fix and improve default argument handling
1. Fix negative octals. Currently not handled correctly by `-py3`
   (unusual case, but incorrect).
2. Fix arguments of type "octal + something" (e.g. `0640 | 04`).
   Currently drops everything after the first octal. Nasty!
3. Fix bool arguments "0 + something" (e.g. `0 | 1`) are always
   "False" (unusual case, but incorrect).
4. Remove special handling of "TRUE" and "FALSE" from
   `convertValue` since there's no reason these have to match
   "true" and "false".
5. Remove the Python 2 vs. Python 3 distinction based on the
   `-py3` flag. Now the same python code is produced for default
   arguments for Python 2 and Python 3. For this, octal default
   arguments, e.g. 0644, are now wrapped as `int('644', 8)`. This
   is required, as Python 2 and Python 3 have incompatible syntax
   for octal literals.

Fixes #707
