Allow node traits to define URLs

[jameshadfield]

This PR extends traits defined on nodes to allow an optional url property, which results in a link being rendered in the tip-clicked panel.

As an example, this allows the following node structure to be rendered as follows:

"node_attrs": {
  "originating_lab": {
    "value": "Area of Virology, Serology and Virology Division (SAViD), New South Wales Health Pathology Randwick"
  },
  "pangolin_lineage": {
    "value": "B.1.1.7",
    "url": "https://cov-lineages.org/lineages/lineage_B.1.1.7.html"
  },
  "recency": {
    "value": "Older"
  },

(P.S. colorings in the dataset JSON provides a title for pangolin_lineage, recency and originating_lab, which results in them being rendered as PANGO Lineage, Submission Date and Originating Lab).

Additionally the code around processing URL strings has been improved and tests added.

Closes #1307

Fantastic, thanks for doing this so quickly! Can you fire up another heroku so I can give it a try? (Or better yet, merge it! :)

[trvrb]

Awesome! This is a nice addition.

[AngieHinrichs]

Thanks again for adding this -- super-useful.

Maybe it's my JSON, maybe I need to wait a bit longer for nextstrain.org to update? but this isn't working for me yet on nextstrain.org, i.e. the value appears but isn't a link to url:

"subtree": { "value": "Subtree", "url": "https://nextstrain.org/fetch/hgwdev-angie.gi.ucsc.edu/cgi-bin/../trash/ct/subtreeAuspice1_hgwdev_angie_99be_256c80.json"}

https://nextstrain.org/fetch/hgwdev.gi.ucsc.edu/~angie/subtreeUrl.json?label=nuc%20mutations:T23155C

This functionality is available in the latest auspice release (v2.25.0) but this hasn't made it to nextstrain.org yet.

It's currently available at dev.nextstrain.org for final testing, and should arrive in nextstrain.org over the next day or two.

[AngieHinrichs]

Ah, I forgot about dev.nextstrain.org! It's working great, thanks so much!
