UI: Use sliders and [0, 1] ranges in ocean modifier

The ocean modifier has two properties that use a [0, 10] hard min and
hard max. The values act as factors though, so it makes more sense to
use sliders and a 0 to 1 range.

This commit also bumps the file subversion to avoid repeatedly applying
the change to the properties' range.
