Add "basic" output format
Add "basic" output format. This outputs the code in the form of a Basic
program that installs the assembled output. If an execution address is
provided to the END pseudo operation, it will transfer control there using
the Basic EXEC command.
Thanks to Tim Lindner <tlindner@macmess.org> for the original patch. I used
it mostly as is except for a couple of minor fixes for coding style and
removing a variable declaration from inside a for() statement for
portability reasons.
