LOAD and RUN alias

[nihirash]

I'd like have possibility load and run something with one command.

I think it can be called 'CHAIN' like in BBC Basic or it's possible execute just by filename in current directory(like *-commands form /mos/).

First way will look more BBCish but second will looks more in common way.

Perhaps the simplest way is to allow a parameter with the filename to RUN so you can *RUN code.bin
