Have mksrcarc.sh log its activity to standard output.

Its previous policy of silence made sense before we did builds using
bob (gratuitous output on success caused cronmail) but now it just
makes it hard to spot problems.

Add 'set -e' to mksrcarc.sh, so it spots zip returning error.

Stop using 'zip -k' to construct the Windows source archive.

It was intended to ensure that people still working with DOS filename
restrictions (or things approximating that, e.g. VFAT) wouldn't have
trouble. Those days are surely long gone, and now zip -k is causing
its own trouble with the new VS2010/VS2012 project files, which
include pairs of filenames that become the same under the zip -k
transformation and hence break the source archive build.

New FAQ, aimed at the people who periodically send us large
questionnaires in unfriendly formats like Excel, apparently in the
mistaken belief that we have some kind of incentive to answer them. I
hope I've managed to identify the key reason why they make this
mistake.
