v0.4.1 - fixed missing apple2e.rom

This 0.4.1 patch release fixes a ROM file missing from the distribution tarball and zipfile.

Many, many improvements, including:

• Added disk drive/controller emulation! Supported file formats: .dsk, .do, .po, .nib
• Added support for Apple IIe (unenhanced/6502), with an 80-column card.
• ^C^C in the tty interface now opens a command interface, instead of quitting
• --tokenize: take AppleSoft program code as input, emit tokenized AppleSoft to output
• Many improvements to bobbin’s built-in debugger (only available in --simple interface)

To build bobbin, we recommend using the *.tar.gz and *.zip files that are not named "Source Code"—the latter are automatically generated by GitHub, while the former include the pregenerated ./configure script and associated helpers, needed to build bobbin. It is also highly recommended that you have a developer package (header files and library symlinks) for curses installed when you configure and build bobbin.

As always, see README.md for much, much more information.
