The buffer-based tokenizer reads the source into memory once at construction, so
the underlying stream fail bit never flips at end-of-input. cParser::ok() was
not stream.fail(), so while( parser.ok() ) loops (TMoverParameters::LoadFIZ and
similar) never terminated -- they spun on empty tokens past EOF, hanging the
vehicle/.fiz load. Redefine ok() as "input still remains" (buffer not exhausted,
or for replay not exhausted), which terminates those loops while staying true
right after opening a non-empty file (the open checks if(!ok())).
