Fix [#33189] AFTER 2.65 - Units in doc strings in ocean modifier.

Also:
* Fixes a (op prop) bug which prevented, once you had baked and freed ocean once, to bake again.
* Fixed infinite values of acumulated foam when baking with foam_fade values above 1.0, now simply clipping accumulated foam value to 1.0, as already done for the "instantaneaous" foam value returned by BKE_ocean_jminus_to_foam().
* Added missing RNA descriptions.
* Made foam_fade unanimatable!
* Added in UI some missing properties that are imho useful: random seed, size (kindof 'surface scaling'), and foam_fade (baking only).
* Removed custom lerp() func from bke's ocean.c, BLI's interpf does exactly the same thing (the first two args are just in reversed order). Note: this could most certainly be done in other parts of the code, bpy's mathutils for e.g. has its own linear interpolation code for vectors and matrices :/).
* Did some general code cleanup (mostly line length and no C++ -> C comments)...
