There are two Apache example configurations now, first is an example for Shibboleth SSO authentication, second is an example for Basic authentication. Using these two examples (especially the latter) it is possible to very quickly set up demonstration installation. The installation page was updated accordingly to reflect new installation options.

The mentat-informant.py module is a Python replacement for previous mentat-briefer.py module. It is designed to provide periodical statistical overviews via email. The email reports are localized using babel package and can be translated into any language. Additionally, the reporting engine uses Jinja2 templating system for message rendering, so it enables very easy customization. (Redmine issue: #3377)

This commit represents huge amount of work and introduces new Python-based version of Hawat web user interface for Mentat system. It is built on top of the great Flask framework. Currently it is still work in progress and many features are implemented only as dummy stubs, however the core functionality is almost finished. Following is a list of current key features:

  * Focus on modular architecture using Flask`s blueprint feature.
  * Multi-layered configurability (defaults, multiple file overrides).
  * Plugin system.
  * Internationalization support.
  * Support for multiple authentication systems.

This commit provides working albeit hollow starting point for future web interface development. IT IS NOT READY FOR PRODUCTION USAGE!!!
