Reinstall swup

[nishidai-andaze]

• [ ] Re-enable SWUP (including swup plugins, etc.)
• [ ] Debug and suppress bugs that occur with page transitions (so that each code does not fire unnecessarily)

Basically revert the code removed in the following commit. https://github.com/andaze/WebCorporate/commit/359cf0087b6d7333bacca149f0a35f7066d62e5b
