[REQ] Changelog file

[rgigante]

Hi Nick,

i think is going to be mandatory to put inside the Indigo distributions a changelog file to keep track of all indigo's mods and improvements.

Thanks in advance, Riccardo.

Here's my two cents

*************************************Indigo 6 test 1*************************************
Scene Changelog:
Old-Code:
<background>
<radiance>1 1 1</radiance>
</background>

New-Code:
<background>
<spectrum>
<rgb>
<rgb>1 1 1</rgb>
</rgb>
</spectrum>
</background>

Changelog:
* speedup with phong pow()s
* added bump mapping for specular mat
* Added multithreading
* Added -t switch to specify number of threads.
* nice error message on out of mem while building kdtree
* using doubles for pdf and radiance stuff
* added colour correction
* background element now takes a single spectrum child element
* can now have only one of background, skylight, or env_map
* made window size equal to render size
* changed default sky gain to 0.002
* changed bidir RR live prob
* decreased num warmup mutations by half
*************************************Indigo 6 test 2*************************************
Changelog:
* changed some stuff so that bump mapping won't hang warmup on dodgy geometry.
* fixed bump mapping for phong that was broken for v0.6 test 1
* Added PNG texture loading
* rewrote bidir stuff
* speedup for objecttree
