Fixes issue 2129 ("can't export as loop with CLI")

Browse Source 
Adds a new command line option to render a song as a loop ("-l", "--
loop-mode").

Also cleaned up the code which parses the command line options by
pulling out methods that print the version and the help.

Updated man page: Added the new option to command line render a loop. Updated
the data of the man page and the URLs.

Added information about option to bypass root user check on startup

Calculate the copyright year dynamically

The command line options for help and version info both print the
copyright as "2004-2014". Until now the value for the second year had to
be adjusted manually. With this patch they are computed dynamically so
that the current year will always be used.
