Use correct headline structure

[acrylian]

The headline semantics are not correct on the theme. It seems you only use h3 headlines which is invalid if there is no h2 or h1 headline. This is also important for SEO.

Generally every page should have one h1 headline. Only on the home page the h1 should be the site/gallery title for SEO. On every other page it should be the page title (e.g. image title, album title, Zenpage page, category or article etc).

All other headlines can be used multiple times abut must follow the proper nesting.

(And yes, the current old official Zenphoto themes don't do everything fully correct either but future ones will.)
