Install the turbogears web gui including an init script. This
patch includes a few related changes:
* create a production configuration
* rename the web gui startup scrip to ipa-webgui
* add an init script
* chkconfig on the ipa-webgui init script
* make the start script properly daemonize the app when not
in a development directory.
* Install everything to the correct places (/usr/sbin/ipa-webgui
and /usr/share/ipa/ipagui mainly).
There are some things still left to do:
* Sort out the logging - the config needs to be adjusted so
that logging messages end up in /var/log.
