Fix for makefile to enter interface dir

New linking order for the 2.5 editor/wm libs

Addition to last commit, now the length of the hair is used to
scale the object. Also, the direction is now derived from the
first and last keys on the hair, instead of first and second.

Whole lot of changes.... here a shortlist:

- removed editors/area and put this all in screen
- added first python calls (note, a new c file for scriptlinks)
- added view3d editor callbacks (no drawing yet)
- added files in editors/interface

(Cmake and Scons has to be fixed, help welcome!)

- now areas/headers are being converted on file read
- note: previously saved 2.50 files will crash!!! (.B.blend)
- area regions are being drawn, first handler for cursor added (on edge)
- window duplicate and scale works correct for screen subdiv

Todos for me:

- need to fix things in syntax (function names) a bit still
- more operators for screen
- define how Context will work... still unresolved when it gets set
- docs!

Reviews of code structure is welcome!
There are also more todos now for others, but it can wait a couple of days

Particle object and group visualization now also work for hair, to
make for example feathers. Also made dupliparts work within groups.

One issue still is that in particle editmode, the duplis can interfere
with brushes and selection, though tweaking the dupli object position
can alleviate the problem.

Blur Node to support Relative (percent) values
This commit makes it possible to use relative values when using a Blur node. There
is a new toggle in the node that can be used to enable the feature.

Thanks to David Millan Escriva for contribution!

Black and White level inputs to RGB Curves compositing node
This commit adds possibility to define black and white level of the
mapping curve of the RGB Curves node. This functionality is exactly
the same found in the Curves tool of the UV/Image Editor. It can be
used to extract wanted color ranges out of the input easily.

Thanks to Björn C. Schaefer for contribution!

Conversion of "Toggle Link" tool to "Make Link"
This commit alters the behaviour of "Toggle Link" tool found in the node
editor so that it only makes link between selected sockets. Links cannot
be deleted by using the tool again as before. Instead deleting links can
be done by using the old method (drag with lmb).

The delete functionality may require further investigation to see if it
should be improved.

Bugfix for difference between surface and particle orco.

Code cleanup - removed unused var that I forgot to remove from bPose struct

svn merge -r 13095:13148 https://svn.blender.org/svnroot/bf-blender/trunk/blender

Merged back with last version where collisions worked at least a bit (rev 12296). Also merged fixes (hopefully).

Bugfix: in the new image function, uv test grid option
didn't draw colored crosses correct.

One-liner fix:

IK-constraint was broken by code cleanups, as it required the pole-target to be set too.

== Auto-IK Improvement (Peach Request) ==

Auto-IK can now operate on more then 1 selected bone at once, (as long as they are not a part of the same chain).

Fix for use of uninitialized variable in shadow caching, could
sometimes give 1 nan pixel.

Check for screen bounds clipping in particle editmode. (thanks to valgrind again)

Used valgrind to find some uninitialized variables
