Add a -V option to display the version information about each

component module.  This is intended for support purposes, so that I
can tell unambiguously what version a binary out in the field is.

Additionally, display a revision timestamp along with the version
number.  This also is intended for aiding in support and is the Unix
time of the latest component module.  Having this, should allow me to
do a "cvs co -D timestamp avrprog" and get exactly the source of the
version that is being reported.
