Title:
  Better error message on startup / drizzled.cc

Status in A Lightweight SQL Database for Cloud Infrastructure and Web Applications:
  Fix Committed

Bug description:
  In drizzled/drizzled.cc several checks are made on startup and if they
  fail then drizzled will abort with an error message.

  For instance if I do

    sbin/drizzled --foo

  then I will get the error

  Aborting:"Use --help to get a list of available options. unknown
  option foo". Abort was called from drizzled/drizzled.cc:1369 in
  init_variables_after_daemonizing()

  This is a result of following code:

    catch (po::unknown_option &err)
    {
      unireg_abort << "Use --help to get a list of available options. " << err.what();

  
  The error message is very confusing, lacks spaces and capitalization. It would be much better if it was worded like this:

  Aborting: Unknown option foo. Use --help to get a list of available options. 
    Abort was called from drizzled/drizzled.cc:1369 in init_variables_after_daemonizing()
