c2317edf8a Revert boost requirement to 1.37 
I don't want to get into testing for tr1::unordered_map, and the
boost compatibility doesn't exist in 1.34.

0a2264cad4 When instantiating effects, copy user data of any created nodes. 
This bug was the cause of the huge memory consumption / death reported at some places:
the BVH data on "raw" .ac models (random objects) was dropped on the floor.

5991195062 optimize creation and sharing of effects 
Implement equality test and hash for for property trees.  In an
Effect, make a hash table of Effects that inherit from it keyed on
their unmerged property tree. Using that, makeEffect() should return a
single Effect for given property tree description. Animations may
change that in the future...

3e40d624a8 Effects for models 
Basically working, at last. Among other things, create effects in
 models loaded directly from .ac files; this can happen, for example,
with the random models from the materials library.

b905f4b8aa Property system optimizations 
Profiling startup with the new effects code exposed some performance
gotchas. The objective is to reduce allocation of std::string
temporaries, especially when looking up node path names. Also, I
changed some paths to initialize strings with strings instead of char *;
this causes less allocation, at least with glibc. Also, eliminate
the old version of find_node and its helper functions by writing the
template version of find_node_aux to handle an explicit index
parameter.

Also, add const char[] as an internal property type

This doesn't actually add a new type to the property system, but allows using
character arrays as arguments to certain templates.
