* Further optimization to the colortree, now allocated in one single chunk of 4090 bytes (2051 times better than original code!).
Not doing all the malloc/frees should be slightly faster, and it also helps with cache locality (the whole tree can fit in the
cache).
* Remove the useless color "balancing" multipliers that did more harm than good.
We still need some improvements on the median cut, or maybe switch to a smarter algorithm; or add some cheats. See the JFIF quirks
for an example.

There is room for optimization and maybe bugfixing.
The cluster table size is now:
511*15 = 7665bytes, this is 1094 times better than the color table.
Please test and report your results !

The 8megabytes conversion table is replaced by an octree taking 10kbytes (800 times better !)
The conversion is done with full 24bit precision instead of 19 bits (8 green, 6 red, 5 blue) previously.
Not added to makefile and integrated yet, because I need to bugfix first.
