Put the application hello.asm on the disk, not the bare metal one

Browse Source 
Both are called hello.asm and they are different programs: Programs/hello.asm
is the 1978-style boot image that writes straight to port 0x00 and HALTs,
and CosmOS/Apps/hello.asm is the loadable one that ends with SWI osExit.
The disk had the first, which assembles to a .bin the shell cannot load, so
watching it work meant taking the file off the disk afterwards.

Now it has the second, and the whole thing is two commands:

    > load Asm.sbx
    > run hello.asm
    wrote hello.sbx: program 22, data 14, labels 3
    > load hello.sbx
    > run
    Hello, World!

It writes over the hello.sbx the host tool put there, so what runs is the
machine's own work. Byte for byte identical to the C assembler's, as ever.

strings.asm stays as it is, and now earns its place by being the odd one
out: no #Include and no #Base, so it assembles to a boot image rather than
a loadable program and the difference between the two is visible on one
disk.

Tests/native.sh still builds the bare metal hello.asm, and should: it is the
only thing that checks the SPBT path end to end, including running what came
out.
