Missing scons include entry.

Fix for hair root transformation: was missing a world/object space
transformation.

Fix display issue

Reimport code from new solver to particles. Result is crappy
and positions are not updated very well, but it's a start.

Disabled hair debugging code, due to excessive memory consumption and
overhead.

This can be implemented much nicer using a hash table and statically
typed solver function templates, but for now just disabled it.

Important fix for damping loop.

This was causing great instability due to using the advanced velocity
after applying spring and external forces.

Now the velocity integration happens in the internal loop, but applies
precalculated spring/ext. forces as constant during the time step,
while incrementally calculating the next velocity.

Hair debugging: Draw vectors as a point with a direction (as opposed to
a line from a to b).

Clear hair debug data when rebuilding the solver data.

Creation code complete - no way to test yet.

Missing struct attribute in function declaration.

Removed deprecated old debug data types and per-thread debug data.

The Debug class now uses a static mutex to prevent race conditions on
the debug elements. This is inefficient of course, but for the purpose
of debugging perfectly fine.

Debugging elements for hair are stored in world space and must be drawn
accordingly.

New debug drawing system for the hair solver.

Now storing anonymous "elements" (dots, lines, etc) instead of explicit
elements of the simulation. This makes it much easier to quickly add
debug information where needed without going through all stages of data
conversion. Could add tagging to associate elements with the
various debug settings again.

Another partial fix for bending problems.

Main requirement is that the frame iterator rotates the initial frame
already for the first curve segment.

More WIP code for particle initialization.

Only remove solver if it exists.

Fix crash with bullet when we remove a hair system solver.

WIP.

Add stub functions to synchronize data between particle system and new
solver.

Only generate new solver if needed in solver step.

Minor fixes and little code for conversion.

Hook up new solver settings to old particle code.

New settings are now exposed in UI and saved/loaded in blend files.
However the solver is not yet hooked up.

To make this work, all references to the old clothmodifier code have
been ifdefed out. This means that the particle simulation will currently
not do anything.

Partial fix for bending force issues: was missing vector normalization.
