Cycles-Bake: fix for regression introduced on: "[review] restoring SAMPLING_PATTERN_CMJ test and adding a
is_baking variable"

The bug was: scenes with more than one object will misbehave.

We can't get the object id before the scene is updated, so we now
set the baking variable before we call bake_manager->init.

Cycles-Bake: Renaming 'Custom-Cage' to 'Cage'

As suggested by Andy Davies (metallandy):

The Custom cage title is not correct. Custom cages are when the user has
modified the topology of the cage by moving verts/topology and meshes
under this slot do not need to have modified verts/topology in order to
work. They could use a regular mesh or have one imported from another
application so just calling it Cage mesh or Cage object would be
perfect. Calling it cage mesh goes against convention for all other 3d
applications so it's just going to cause confusion.

Cycles-Bake: [review] float promotion cleanup, store swizzle sign as float

Cycles-Bake: Move "Output File" section to the bottom of the bake panel.

The reason for this is heirarchy. During the order of operations the output file is likely one of the last
things you'll set. First the type and width, then margin, then specifc settings, and finally the output file.

Doing this also helps avoid breaking up the settings that are specific to baking, such as the Type and "Selected to Active".

Cycles-Bake: divide the in/direct passes by the color passes

Otherwise the in/direct passes are 'contamined' by the texture/color of
the faces.

Implementation Notes:
---------------------
Baking for Cycles was implemented in two fronts:

In Blender we created a new operator that will try to bake using the current engine.
So far only Cycles has this implemented, but other engines (even the Blender Internal) could go through this API/pipeline.
The operator is responsible for the image handling, normal space
transformation, populate the UVs, loop over faces, ...

In Cycles we extended the baking functionality available for environment
and displacement for the other render passes (not all of them since some
of them doesn't make sense for baking).

The API is simple. Blender send a populated array of BakePixels to the
renderer, and gets back an array of floats with the result.

BakePixel is tjhe following struct:

struct BakePixel {
int primitive_id;
float u, v;
float dudx, dudy;
float dvdx, dvdy;
};
