fix catalyst's abort of so work

Hello.

I've tried the Log::Log4perl::Catalyst, but it does not seem to work well.
Catalyst::Plugin::Static::Simple has been using the $c->log->abort(1), but since this is not work, it does not hide.

I tried to write a patch.
I was compared to http://cpansearch.perl.org/src/VANSTYN/Catalyst-Runtime-5.90071/lib/Catalyst/Log.pm

Thank you merge if there is no problem.

Cheers,

This will call Log::Log4perl::Catalyst's abort() method, which, when called with no arguments, will always return undef, so the if clause will never be run. Are you sure this is what you want?
