59: Update header design and layout

[miina]

Fixes #59.

• Uses header with search for archives and adventures post type.
• Adds breadcrumbs to taxonomy page;
• Adds title to search page.

Todo:

• Styling fixes

The search page looks like this:

However, the taxonomy and adventure page look like this and need styling fixes -- for some reason any change made to the adventure.css or archive.css breaks the style, the style fixes are added only to search.css

@kienstra This PR should be ready other than styling issues.

@mehigh Do you think you could review the header, breadcrumbs, and the title's style? The search page needs just a review but adventure and archives page need styling fixes, too -- for some reason here as well as in #64, any change I make to adventure.css or archive.css breaks the style, would be great if you could help with that.

Edit: Looks like archive.css looks better after the last change, however, the adventure.css is completely stripped if I make any changes, so this still needs some attention. Currently the header looks like this:

Basically the difference with other pages is missing this:

.search-travel-btn,
.search-travel-btn:visited{
    margin-left: 25px;
    color: #8b58e3;
}
.travel-date-input{
    line-height:0.125rem
}

Not sure why this breaks the CSS on adventure.css.

@kienstra Thanks for reviewing, the changes are made within 6f5c870.

@kienstra and @mehigh Added the missing style change for adventure page as well now, the style just needs reviewing now (and any fixes that Mike might find necessary).

Approved, Other Than Styling Review

Hi @miina, Your latest changes look good. As you mentioned, this could still a look from Mike. But other than that, it's approved.

Request For Retro Sanity-Check

@mehigh, if you have time, could you do a quick sanity-check of the styling here? The styling appears well on the archive.php, search.php, and single adventure pages.

But otherwise, I think this is ready to merge.

CSS looks OK, thanks for the work here @miina !
