Version 1.4 - Opening database

[jannis]

Hi, version 1.4 is here. It includes the following changes:

• Opening database
  
• Make profile page invisible for anonymous users
  
• Detect invalid user sessions
  

The opening database / opening book will be enabled if you click on the book icon in the analysis board. It looks like this:

   

The entries show how often the move was played. The white and black bar show in how much games white or black had won if this move was played. You can click on one of the entries and explore the openings of online games. Currently the maximum depth of the opening database is set to 10 moves.

Some cool server stats:

• 90 registered users (including 4 Bots)
  
• 2393 recorded games
  
• 12K opening database entries
