Install the web gui

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.
