* Changes to the script engine:

- script ends when run_func can't find the buildin command. (script engine error)
- run_script_main doesn't change RERUNLINE to RUN automatically, the buildin command that set it is responsible for that now. The buildin command can use this to detect a rerun.
- created functions to alloc/free a script_state.

* Changes to the script engine: [FlavioJS]
- script ends when run_func can't find the buildin command. (script engine error)
- run_script_main doesn't change RERUNLINE to RUN automatically,
the buildin command that set it is responsible for that now.
The buildin command can use this to detect a rerun.
- created functions to alloc/free a script_state.

* Added missing command #delitem. [SketchyPhoenix]
* Fixed charcommand behavior where those that can accept a name with no additional parameters
