bo-tracker and bo-data core dump with invalid command line options

[Gabo]

Starting bo-tracker or bo-data (v 1.0.3) with invalid command options

bo-tracker -h

or

bo-tracker -?

thows error message and core dump:

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::program_options::invalid_command_line_syntax> >'
  what(): required parameter is missing in 'server-host'
Aborted (core dumped)

I'd like to see more clear error message "invalid command line option -h. See bo-tracker --help for help." instead of core dump.

This is minor bug but core dumps launch Apport in ubuntu 12.04LTS.

The error message shown is already clear enough. In the case of bo-tracker -h is used to set the server hostname/address and this parameter is clearly missing.

The "help" output is displayed now for any error during parsing of arguments.
