increasing loglevel under production
* cache log uninformative in production
* added $ENV{STARMAN_DEBUG} FTW
Merge branch 'staging' of github.com:WormBase/website into staging
Added support of Server::Starter daemon to control starman.

* cleaned up configuration directives. The installation_type is no
  longer in use.
* The installation_type specific log4perl files are no longer in use
  in favor of a single shared file. Log level will be controlled by
  a single config directive (work forthcoming)
* added the logs directory and a quick README of contents therein
* standardized the names of log files
* added a new Server::Starter daemon (script/wormbase-daemon.sh)
  that will make sure starman is running at all times
* various other housekeeping edits to reduce number of hard-coded paths
  and distinctions between install types. One app install should be
  like any other and tweaked during launch.
