possible fix for os x problem, caused by SIGVTALRM

Modified 'make release' as recommended by J. Walton (removed some @'s)

"Fixes" bug 929 - The undo system crashed when the maximum number of undo
steps in userprefs was set to 1. Increased the lowest possible value to
2 :)

SCons for irix update (now does mips3 binary).

Fix for irix 'make release'

SCons update
* makesdna generates dna.c which in turn should be compiled with nice cflags,
linkflags etc. But, a small error slipped in which caused the .c file to be
compiled into a nice .o file without those flags.
Thanks to Hos for pointing out the error and persisting there indeed was an
error.

arealight now can be used without global photonmap
fixed problem with spotlights not rendering

Fixed a typo in the 'make release' stuff

A few 'make release' related modifications:

* the compiled plugins get moved to .blender/plugins in the
release tarball (the include and C files remain where they
were). Please test.

* if they exist, the directories release/scripts and release/bpydata
get copied to .blender/scripts and .blender/bpydata respectively.

Python bug fix for #724
* Blender.Object.setDrawMode does not work. I had accidentally switched the
variables for setDrawMode and setDrawType. This implied that _both_
functions did not work correctly. The functions getDrawMode and getDrawType
use the correct variables.

Python bug fix for #875
* Blender.Object.GetSelected() would crash when no 3d-view has been
initialized at startup. Fixed.

- Port fix for Backbuffer/Optimize hang (caused by short pointer hack)
from tuhopuu.

Applied checks for more secure 3D font handling.
(Loading fonts without a valid name would crash Blender)

- code i committed for correct arrowkeys on selecting items in pulldowns
broke the ui_mouse_motion_towards_block() function. This made sure
mouse motion (diagonal) towards a new opened sub-level keeps the sub-
level open.
Fixed!

- Nurbs curve/surface Nkey editmode now displays the W value again!
was lost in 2.30 makeover.

- commented out line with unused variable, to make warnings going down
with 1!

Added another control for new pathlight refinement parameter and solved
a problem with name collision betwen textures and shaders reported by kino.

- moved declaration of new variable up; in plain C you cannot do that
in the middle of code, only after a "{". :)

* Fixed an incorrect hotkey label in the 3D view menus
and toolbox

* Small tweaks to the default theme's colours
