Lot of code... 2 new features:

1) Curve deform
http://www.blender3d.org/cms/Curve_Deform.392.0.html
Works simple as expected, but keep track of the rotation axis
in F7 buttons (Track X Y Z)
Only Mesh deform supported now.

Code changes:
- centralized deformation calls in curve_modifiers() mesh_modifiers()
etcetera. Here also other effects can be added like wave. Now the
evaluation order is fixed, but should become optional. It also doesnt
use the Displist anymore as deform-input. That latter part is unfinished
yet.
This code also is used for Hooks and will be needed for softbody

- made convention stricter that displists are being checked on in
drawobject(), this to prevent routines to make new displists recursively
(like armature does). Now a freedisplist() is sufficient to signal that
a new displaylist should be made.

2) Object Hooks
http://www.blender3d.org/cms/Object_Hooks.391.0.html
Support for Hooks is added to Mesh, Lattice, Curve and Surface objects.
For Armatures this would require some more work & research.
Main goal for this feature is to provide quick & simple access to the
underlying geometry in Objects on Object level, supporting hierarchies and
Ipos etc.
