Version 0.11.1

"Cleaning up, vol. 2" edition:

Enhancements:

• Create a proper decorator registry for the syntax machinery.
  • Can now register priorities for custom decorators to tell the syntax system about their correct ordering (for sort_lambda_decorators, suggest_decorator_index).
  • Register priorities for (some of) unpythonic's own decorators using this new system, replacing the old hardcoded decorator registry.
  • Now lives in unpythonic.regutil; used only by the syntax subsystem, but doesn't require MacroPy just to start up.
• Try to determine correct insertion index for trampolined and curry decorators in macros that insert them to decorator_list of FunctionDef nodes (using any already applied known decorators as placement hints, like a programmer would).
• namedlambda: recognize also decorated lambdas, and calls to curry where the last argument is a lambda (useful for looped_over et al.).

Breaking change:

• Remove the special jump target SELF.
  • Was always a hack; no longer needed now that v0.11.0 introduced the general solution: the withself function that allows a lambda to refer to itself anywhere, not just in a jump.
  • Now the whole thing is easier to explain, so likely a better idea (ZoP §17, 18).
