Hair Particles: DNA: Add properties for new GPU hairs.

Hair Particles shape properties are ported from cycles. Thoses properties
have the same defaults and have a do_version of their own. Cycles will use
theses properties instead of its custom ones.

Some realtime engine specific settings are also added to scene->r because
it's much easier to control as global values.

Bumping Version number so cycles can do its own do_version on top of the
default settings.
