*The narrowui value was hard coded in all ui scripts, made an user preferences option. Basically this value determines on which area width, it should switch between dual/single column layout.
ToDo: The Changes only take effect when reloading scripts/restarting Blender (after saving as default). Will maybe add the "Reload Scripts" operator next to the button in the future.
* Small fix for Fluid Add Button, when in single column mode. Didn't expand like the other "Add" Buttons.
Running scripts directly didnt call the register function, even though this is not essential its good to be able to run a script directly and see changes in the UI.
- remove functions such as operator_int(), operator_enum(), operator_string
this mixed with keyword arguments in a way that made them hard to read.
Instead, have operator() always return properties rather then needing an argument.
- rename prop_pointer() --> prop_object(), pointer is more a C thing.
- missed item_enumR(), rename to prop_enum()
Contributors list isnt used much in our C code so probably its easier if people just use svn blame for this.
Can change if this isnt acceptable but I guessed people didnt care so much since most scripts had no header.
