GUI issues from #193

[mtwente]

Current Behavior

I just noticed a few GUI issues on the browse page that were accidentally (re-)introduced by #193.
If I come across more stuff I'll add it to this issue.

• line 116, search box

filterButton.focus(); (which was the CB standard setting) should be changed back to filterTextBox.focus()

• line 106, items number
  In the current setup, translations were lost. Change back to language-independent

document.querySelector("#numberOf").innerHTML = `${filteredItems.length} / {{ items | size }}`;

• line 79, View Full Record button
  In the current setup, English text is hardcoded and the button colour changed. Change back to outline-primary button and use translation variables as before:

    card += `<hr><a href="${itemHref}" class="btn btn-sm btn-outline-primary" title="link to ${obj.title}">` +
            `{{ site.data.translations['_includes']['js']['browse-js.html']['view-full-record'][site.lang] | default: 'View Full Record' }}</a>`;

• additionally: remove the navigation buttons left/right on the compound object pages.
