Revert "restyle of optaplanner-website": I need to publish the website today and this big bang blob change wasn't vetted properly (no discussion, no PR, no peer review, no acceptance). It might introduce regressions. This commit needs to be supplied though a PR.

This reverts commit b5b8a0cc2abeb2afa9bf51c7c784b48e2b0fe95d.
