Several related changes: - stdlib.tolk is embedded into a distribution (deb package or tolk-js), the user won't have to download it and store as a project file; it's an important step to maintain correct language versioning - stdlib.tolk is auto-included, that's why all its functions are available out of the box - strict includes: you can't use symbol `f` from another file unless you've #include'd this file - drop all C++ global variables holding compilation state, merge them into a single struct CompilerState located at compiler-state.h; for instance, stdlib filename is also there
