Bug fixes

for..in now allows accessing collection items by pointer
Error handling:
- error() is removed
- exit() now accepts an error code returned to the OS and an optional error message
- umkaRun() and umkaCall() now return an error code (0 on success)
- umkaAlive() is added to check if the interpreter can still execute umkaRun() or umkaCall()
- std.Err, std.error(), std.exitif() are added for graceful error handling
Unicode support:
- printf() on Windows fixed
- Locale parameter in umkaInit() is deprecated
