Day 10

continue to fill main() function and run Viewer

implemented gos_CreateMemroyHeap and friends

caveat: _open() calls File::open(const char* bufer, int length) instead of system open because

#define _open open

should be

#define _open ::open

or even better

#define _open my_super_open

and then

FILE* my_super_open(...)
{
    ...
}

caveat2: code uses long and assumes that it is 4 bytes :-(
