- Changed player colour JS interface: setColour(...) instead of a colour property - Introduced a network log and replaced most network LOG() calls with NET_LOG() - Moved to a slot-based system for Pre-Game and extended a lot of the JS APIs to networking stuff - A bit of cleanup in the low-level network code (Unix parts) - Clients now keep track of all other connected clients on the server (And exposes this info to JS) - Split out GameAttributes to its own file - Removed unused class AttributeMap - Changed CJSObject to use T* pointers in JS_SetPrivate (needed to make ToScript work with multiple inheritance) This was SVN commit r1929.

A simple read-only JS wrapper for map types (STL associative containers).

Has been tested with integer keys. Writeability shouldn't be all that hard

to add, it's just not needed by the current users of the class.
