Libraries (stdio, unistd) are now encapsulated in context
Console-call rebuilded and moved. Better integration with help.
Type block! added for output and error redirection.
There is a bug in function read-from-pipe. It can loose end of buffer data.
The right way todo is to check errno, but there's no access to external vars in Red/System.
No workaround found for the moment.
FIX: libs encapsulated in context
FIX: Call, better console integration
