build(deps): bump rayon-core from 1.7.0 to 1.7.1
Bumps [rayon-core](https://github.com/rayon-rs/rayon) from 1.7.0 to 1.7.1.
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a href="https://github.com/rayon-rs/rayon/blob/master/RELEASES.md">rayon-core's changelog</a>.</em></p>
<blockquote>
<h1>Release rayon 1.3.1 / rayon-core 1.7.1 (2020-06-15)</h1>
<ul>
<li>Fixed a use-after-free race in calls blocked between two rayon thread pools.</li>
<li>Collecting to an indexed <code>Vec</code> now drops any partial writes while unwinding,
rather than just leaking them. If dropping also panics, Rust will abort.
<ul>
<li>Note: the old leaking behavior is considered <em>safe</em>, just not ideal.</li>
</ul>
</li>
<li>The new <code>IndexedParallelIterator::step_by()</code> adapts an iterator to step
through items by the given count, like <code>Iterator::step_by()</code>.</li>
<li>The new <code>ParallelSlice::par_chunks_exact()</code> and mutable equivalent
<code>ParallelSliceMut::par_chunks_exact_mut()</code> ensure that the chunks always have
the exact length requested, leaving any remainder separate, like the slice
methods <code>chunks_exact()</code> and <code>chunks_exact_mut()</code>.</li>
</ul>

Make url for "client" referrer mandatory
<!-- Please describe your changes on the following line: -->
I added a url attribute to `Referrer::Client` so that the referrer header can be set accordingly when fetching.
`Referrer::Client` has to be kept separate from `Referrer::ReferrerUrl` as they differ in this method

The background color for the tree column headers is drawn using the
system APIs, but the foreground uses custom colors, which didn't follow
theme. This can lead to unreadable text with specific colors, e.g.
leading to black on black.
Fix this by using system colors for the foreground as well. It also
adds on-hover styling to match possible background change on hover.

Rather than waiting until parsing another id (successfully or
unsuccessfully).
If we error before we even get to PropertyId::parse, we'd incorrectly
associate the error with the wrong property, incorrectly omitting it
sometimes.
