This branch adds mostly organizational improvements to the node system by renaming the node folders and files. A couple of internal features have been added too.
Detailed information can be found on the wiki page:

types should now use the node_type_* definition helpers to initialize their bNodeType structs.

- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.

the gamma was inverted. fixed.

work linear/srgb conversions need to be done which that nice since it has to convert from/to the color spaces each time, after quite a lot of testing I think its the best way to go.
The problem was that typical lift values (0.5 - 1.5, in our case ) would over saturate shadows so that even minor adjustments would give unusable results.
tweaking the input lift to compensate for this helped with the shadows but would loose the color adjustments for the mid-tones.

lift for values above 1.0 was too intense.
Use: 1 + ((lift-1) * (lift-1)) so 2.0 is still a full lift but 1.x isnt so strong.
Changed color picker to give more precission, we were having to edit the buttons to see what the numbers were.

- In my changes lift was acting like a second gamma.
- In blender 2.4x it was being added which gave ugly clipping.
- in Magic Bullet Looks it scales the color about 1.0: (col - 1 * (2-lift)) + 1
Did more testing and made sure the order of applying lift/gamma/gain works the same as MagicBulletLooks (tested on Collin's mac laptop).

changes from sequencer applied to compositor mostly noticable is how the lift works.
Before & After,

even with lower values these kinds of errors can be seen.

0.0-2.0 range
(default 1.0), like the other controls. Thanks!

* The Lift/Gamma/Gain formula previously was incorrect, fixed this and
removed conversions - now the RNA values are the same as what goes into
the formula.
* Because of this, added the ability for the Value slider to map to a wider range
than 0.0-1.0. The black/white gradient remains the same, in this case just
indicating darker/brighter rather than absolute colour values. Also added ability
for color wheels to be locked at full brightness (useful for this case, where the
color value itself is dark).
* Added an alternate formula - offset/power/slope (asc-cdl). This fits the standard
Color Decision List formula, here for compatibility with other systems, though
default Lift/Gamma/Gain is easier to use and gives nicer results.
