uncompyle6 2.13.3 2017-11-13

Overall: better 3.6 decompiling and some much needed code refactoring and cleanup


- Start noting names in for template-action names; these are
  used to check/assert we have the right node type
- Simplify <import_from> rule
- Pypy 5.80-beta testing tolerance
- Start to clean up instruction mangling phase by using 3.6-style instructions
  rather trying to parse the bytecode array. This largely been done in for versions 3.x;
  3.0 custom mangling code has been reduced;
  some 2.x conversion has been done, but more is desired. This make it possible to...
- Handle EXTENDED_ARGS better. While relevant to all Python versions it is most noticeable in
  version 3.6+ where in switching to wordcodes the size of operands has been reduced from 2**16
  to 2**8. JUMP instruction then often need EXTENDED_ARGS.
- Refactor find_jump_targets() with via working of of instructions rather the bytecode array.
- use --weak-verify more and additional fuzzing on verify()
- fragment parser now ignores errors in nested function definitions; an parameter was
  added to assist here. Ignoring errors may be okay because the fragment parser often just needs,
  well, *fragments*.
- Distinguish RETURN_VALUE from RETURN_END_IF in exception bodies better in 3.6
- bug in 3.x language changes: import queue va import Queue
- reinstate some bytecode tests since decompiling has gotten better
- Revise how to report a bug

uncompyle6 2.13.2 2017-10-12

* some routnes here moved to xdis. Use the xdis version
* README.rst: Link typo Name is trepan2 now not trepan
