Renamed CreateObject() to CreateObjectAbove() and replaced all occurrences in script files.
Added CreateObject(), the function may need a rewrite though, see comment in code.
Updated documentation
* Plane with same color in all missions
* Sequence multiplayer fix
* Heavy smoke is a particle parameter
* Goal graphics fix
* Fix rocky pick direction after dialogue initiation from left
* Dialogue supports sections
* Hat moved to decoration for other missions
* Dialogue is blocked for a short time after it was stopped, so players don't restart it accidentally
* Broadcasting option to all players for important dialogues
* Speakers face each other
* add_attention parameter for SetDialogueProgress
I would prefer to render the models for speaker portraits directly. However, it seems like it's not currently possible to clip or render models to offscreen surfaces.
