Added extensions of new database engine for C++ (sqlite-based) from
Visual Studio 2015
(Tools - Options - Text Editor - C/C++ - Experimental - Enable New
Database Engine)
Castalia is a free plugin for Delphi since XE7. It uses *.stat files to
save statistics of the IDE usage for each project (compile time, debug
time etc.)
It is safe to delete it, and it is useless to move *.stat files between
developers (each developer has its own IDE statistics).
