Switched Apple II output format to AppleSingle.

Browse Source 
Although the primary target OS for the Apple II for sure isn't DOS 3.3 but ProDOS 8 the Apple II binary files contained a DOS 3.3 4-byte header. Recently I was made aware of the AppleSingle file format. That format is a much better way to transport Apple II meta data from the cc65 toolchain to the ProDOS 8 file system. Therefore I asked AppleCommander to support the AppleSingle file format. Now that there's an AppleCommander BETA with AppleSingle support it's the right time for this change.

I bumped version to 2.17 because of this from the perspective of Apple II users of course incompatible change.

containing DOS 3.3 as well as ProDOS 8.
For ProDOS 8 system programs the load address is fixed to &dollar;2000 so there
is no need for a header. Thus the linker configuration

omits the DOS 3.3 header. The right AppleCommander option to put system files
without a header on a ProDOS 8 disk image is <tt/-p/.
