Merge pull-request from mittorn with small tweaks

Merge the pull-request from mittorn with some some small tweaks
(remove debugging output of layer id, fix switching to 16bpp mode,
bump version in program output). I have a reintroduced a precompiled
binary (which I imagine can be convenient in certain situations), but
moved it into the bin/ directory; the .gitignore file (blocking
the binary) has been removed.
