After this all code related to MongoDB is gone and database migration from MongoDB to PostgreSQL is no longer possible. I have kept the documentation page about migration for now, so that the users can still at least find the information. (Redmine issue: #4225)

The database migrations for IDEA event database *mentat_events* are now implemented. I have moved this issue to the next release, because there is code already merged in the current development branch that depended performing the migrations on target system. It was a choice of either removing that commit, or going forward with implementation. I have decided to implement it immediately, because this issue is blocking many more features.

The implementation is again based on Alembic tool, which is already being used for migrations on mentat_main metadata database. It is however separatelly configured instance, merging both instances into single one would require considerably more amount of research and work.

I have also updated accordingly manual pages regarding installation and upgrading. Very important bit of information was stamping the database with latest migration revision after clean installation.

Certain key categories (IPs, abuses, ...) in pie chart dataset tables have associated context search actions that provide user with ability to quickly search different parts of the application. (Redmine issue: #4321)

With future improvements of database schema there must be a mechanism for performing database migrations. Problem is we have two databases, one accesed via SQLAlchemy and the second directly via Psycopg2. I have selected to use Flask-Migrate plugin built on top of Alembic to perform metadata database migrations. (Redmine issue: #4230)

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!!!
