version 8.8.1
Patches a few nasty issues found since the last release that couldn't wait for the next full release.
- fix compiler crash on hoisting certain variable declarations from inner scopes to subroutine scope.
- don't remove non-trivial initialization assignments for unused variables
- don't remove consecutive assigns to certain memory locations or memorymapped vars (I/O space)
- now able to compile "not xx in array" expression (for 6502 targets)
- "xx not in array" is not synonymous for "not xx in array"
- as a bonus, includes an updated "christmas season" snow example
