Bump version # to 1.2.3

Both ./install.sh --version and caf --version output the VERSION
argument from "project" statement in the top-level CMakeLIsts.txt
file. Immediately before this commit, git clones show a number that
matches the most recent release even though new commits have
happened. This commit bumps the VERSION from 1.2.2 to 1.2.3 to
distinguish the current development version from the most recent
release and the upcoming release.

CMake apparently barfs on version a version number of the format
"1.2.3-prerelease".  If we seek to distinguish git clones between
releases from the released versions, then we will need to bump the
version number both just after release and just before
release. Starting from the current state, this will have the effect
that version numbers ending in an even number are released versions
and those ending in an odd number are between-release versions.
