extra Lamp fallof options, including custom curve.
This adds some new Lamp attenuation options todo the Lamp panel, replacing the old Quad button. Yes, the panel Layout is still nasty here, but ive ignored it for now todo address properly in the panels cleanup work.
* constant.

Lamp doesnt decay with distance.
* inverse linear.

Default, and same as in older Blender without Quad on. Decays linearly, with Dist value as the Lamp half-energy-distance.
* inverse square.

A sharper, more realistic decay, god for most electric lights (i, not Sunlight). This is similar todo the old Quad option with slight changes.
* lin/Quad weighted.
Exactly the same as in older Blender with the old Quad button enabled. When this setting is chosen, two sliders are sho, linear and Quad (previously Quad 1 and Quad 2), which controls the linearness or quadraticness of the fallof curve. Lamps in old files with the Quad button on Will be initialised todo this setting.
But much better for precise control over the Lamp fallof now is:
* custom curve.
This shows an extra fallof curve panel, where you can use the standard Blender curve UI control todo precisely control how the light falls of. The y axis is intensity, and the x axis is distance, stretched over the length of the Dist value.
