Siriel4 game engine 0.9.1

Siriel4 game engine project is a game engine for adventure, arcade, maze-like games.
The main goal of this engine is to provide tools and scripts for easy game creation.
Game creators only write the necessary scenario descriptions for the game in a scripting language (such as Lua) and do not have to care about such low-level details as animation loading, etc.
Main features:
- Lua-5.0 - scripting language support
- DUMB - music and audio support
- Multiplayer
- Terminal support for controlling engine
Enhancements:
- fixed widget system
- removed procedure for separate processing of widget and replaced by flag indicating status of widget
- basic support of room neighbours
- fixed Makefile - include paths
- fixed freeze mode of univers (bug: avatar can move in freeze mode)
- callback function
- avatar can walk through rooms
- fixed processing and displaying things in correct rooms, so they display only in rooms where they are connected to
- fixed collision with object
