Deleted ESCHotspot (use ESCItem instead)

Moved duplicated movement code from ESCPlayer and ESCItem/ESCHotspot to its own script.
Added talking animations management.
Fixed bug: character was turning to last_direction after talking, if coming from another direction than speaking direction.
Continued removing unfree stuff.
