HTML UI issues from #92 (mini.css)

[justb4]

Several issues found, some were there already before #92:

1. Stale links when navigating with Next|Prev through Collections

• navigate to http://localhost:5000/collections/lakes/items
• click in table on id single Item, Ok, shows single Item
• back to http://localhost:5000/collections/lakes/items
• click Next: ok, navigates to http://localhost:5000/collections/lakes/items/?startindex=10
• click single Item Id in table. e.g. id 10
• navigates to stale link: http://localhost:5000/collections/lakes/items/items/10

NB this was already seen before #92

2. Ditto for single Item

• navigate to http://localhost:5000/collections/obs/items/238
• HTML+Map single Item shows
• click Next or Prev button
• Tries to show: http://localhost:5000/collections/obs/items/238&f=html which fails

3. JSON OpenAPI doc link

• go to http://localhost:5000/
• click the link the OpenAPI definition as JSON
• opens http://localhost:5000/api showing HTML i.s.o. JSON (when #101 as well integrated)

Not sure what the standard requires, or if http://localhost:5000/api?f=json should be explicitly rendered?

Problems 1) and 2): some html links have trailing slash '/' in page URLs. In those cases relative links within the page get expanded to URLs with 'items/items..' i.s.o. 'items/..'. . Will solve.

Item 3) : depends on content negotiation, default would be JSON (e.g. curl http://localhost:5000/). But in browser would be HTML, so need explicit f=json when HTML is rendered.

Can close IMO, pls re-open if still nav errors as listed above found.

Still stale links in map markers, caused by https://github.com/geopython/pygeoapi/blob/master/pygeoapi/templates/items.html#L85 . One-liner fix needed similar to regular HTML ft id links in table view. Will fix.

To reproduce:

• open Point dataset with multiple pages in browser
• open HTML view on first page
• click link to Next Page
• click Marker in Map, popup opens with link to single Feature
• click link text in Marker
• 404 error as URL shows something like http://localhost:5000/collections/<dataset>/items/items/feature.11?f=html

Fix is similar to fix in table View in items.html.

Closing, pls re-open if still nav errors as listed above found.
