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.
