fix build on systems with Perl > 5.12.0 (Ubuntu 11.10 Oneiric, Mac OS X) due to split() incompatibility

thanks mauke from #perl on freenode!
from http://perldoc.perl.org/perl5140delta.html
"split() no longer modifies @_ when called in scalar or void context. In void context it now produces a "Useless use of split" warning. This was also a perl 5.12.0 change that missed the perldelta."
Update debian packageing to create scribe user.
Added status command to scribe init.d file.
updated changelog
Fix scribe_ctrl script
Added signal handlers for stopping/reloading scribe.

When we added ssl support we ran into some issues with puppet trying to communicate with
scribe to get it to apply new config changes etc.  Specifically puppet
didn't know when to use the SSL params for the scribe_ctrl program
and when not to.

Scribe will now listen to SIGTERM and SIGUSR1 to stop and reload the config (respectively).
