Version as a special variable w/patch

[Armin Wolfermann]

Hi,

I hope I'm not the only one in need for an easy accessible cfengine
version string. This patch gives you a ${version} special variable
evaluating to the running cfengine version (eg 2.1.5):

diff cfengine-2.1.5/src/cf.defs.h cfengine-2.1.5-1/src/cf.defs.h
