This commit marks the first production release of Mentat system 2.0.0. After lots of work we have finally successfully abandoned the original implementation written in Perl and using MongoDB as database backend.

This commit also marks the end of an era of frantic coding. Until now some of the guidelines and best practices for coding and committing were violated in favor of faster development. This was also possible thanks to the fact that there was mostly only single developer working on the project, so there were no possible conflicts. From now on however things will be back to normal state.

This patch introduces huge amount of work related to Hawat web interface. I was just clicking through the interface and trying to improve everything that popped out at the moment. There are following improvements:

* Enabled DataTable localication plugins.
* Implemented common layout for object management views (list views).
* Redesigned application menu implementation.
* Enhanced application menu to support contextual item action menus in listing tables. All administration list views now use it to generate contextual action toolbars.
* Menu object is now used even to generate breadcrumb menus.
* Simplified working with view icons and their propagation into action menus.
* Implemented AJAX spinner and used AJAX to fetch raw report data to web interface. There is stil a lot of room for improvements, the idea is for the user to be able to inteligently browse through the loaded data in some way.
* Redesigned object administration views (users, groups, filters, networks).
* Cleaned up list of built-in icons.
* Improved web interface translations after the changes in this commit.
* Fixed the bug in serving report data files.

Had to return back the third level in versioning schema because npm aparently can not cope with only two levels...sad, very, very sad. It took me an hour to find out why npm suddenly refuses to install node modules on our automated build system. (Redmine issue: #3387)

Additionally we have abandoned the third level of versioning. The Mentat project is not that big for that to be necessary, for deployment builds there is always another version level added by our automated build system. (Redmine issue: #3387)

The Dashboards module in Hawat user interface now contains prototype implementation for calculating and viewing overall event processing statistics. The module design is based on original Perl-based interface with many enhancements both on the surface (interface) and in the backend code. The work is not yet finished, some of the tasks that remain to be done are:

* Links from data tables to other modules of the interface.
* Missing sorting arrows in data table headers.
* Interface tweaks.
* Chart descriptions and/or help texts.
* Search form tweaks or changes (current implementation is maybe too powerfull for general user).

The libraries for web user interface implementation will be managed using the yarn package manager (currently recommended on Bower site). The package.json file now contains list of libraries that are/will be needed for user interface. (Redmine issue: #3387)
