zt-bcc 0.10.0 alpha 8:
* Added a `char` alias to `int` as syntactic sugar.
* Added support for the `return` statement inside scripts.
* Added support for the BUSY script flag.
* Added FIXED_MIN/MAX to libbcs.
* Added Q-Zandronum defs to zcommon.
* libbcs memory functions can now be exported if using hub/global pointer spaces.
* LIBBCS_ARR_EXTRA now defaults to 8 for faster dynamic array operations.
* Moved INT_MIN/MAX to libbcs.
* Removed changes for libGDCC compatibility as they broke allocations.
* Update errors to say `internal` instead of `private`.
* Update outdated and/or broken zcommon definitions (thanks, FusedQYou!).

Known bugs:
* #if preprocessor directive causes issues with character literal parsing. It's recommended to not use it for now (#ifdef and the rest work fine, however).
