Patch to add a timestamping and version option to femon

Hi,

as I have been in need for a monitoring tool, to check the (in)stability of my
SAT-DVB setup I came across femon of dvb-apps. As it doesn't has a timestamp
option I haven't been able to correlate the outage of video with a signal
reported by femon easily.

Therefore please find attached a patch which adds a timestamping option (-t)
to femon.

It also adds a version option (-v) as you stated somewhere on your homepage
this would be needed. Be carefull with the compiletime/date line. It will
break the debian reproducable build system.

Kind regards

    Daniel
