*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.
Stopped curves 'caps' properties from being greyed out when the curve is 3D -
there's the totally obscure feature where turning off 'Front' and 'Back' turns the
3D curve into a tube.
Would really like this feature to be implemented in a less bizarre way, but
for now it should be enabled in the UI at least.
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.
This was previously only available from the datablocks viewer, but this is the direct replacement to the badly named 'speed' ipo-curve in the past ('speed' implies a rate that must be integrated/added to the results of past frame, rather than a factor).
Also, tweaked the RNA definition so that this shows as a slider (i.e. a factor), since the valid values for this are clamped to the [0, 1].
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.
