Ocean Sim modifier patch
by Matt Ebb, Hamed Zaghaghi
This adds a new Modifier "Ocean" to simulate large-scale wave motion.
Details can be found in the wiki documentation [1], the project homepage [2]
and the patch tracker [3]
The modifier is disabled by default for now. To enable it, the WITH_OCEANSIM
(cmake) / WITH_BF_OCEANSIM (scons) flags have to be set. The code depends on
fftw3, so this also has to be enabled.
