Split plugin details into a separate page

Split plugin details into a separate page

This modifies the `GPluginGtkView` into a stack, showing the list of plugins by default (called the 'overview'), or a page for a specific plugin. Going back and forth is automated, but an application can request the page for a plugin directly if needed.

The plugin row no longer expands to show details or shows a config button, but its activation goes to its own page now. This also makes each row a bit more balanced vertically, since there's no `GtkRevealer` taking up invisible space underneath.

The new plugin page is _mostly_ a copy of the previous plugin row, except:

* It's always expanded (or rather, it cannot be collapsed.)
* The main details are re-arranged a bit to fit nicely on a page.
* All information is found via `GtkExpression`s.
* Instead of separate labels for each author/dependency, these are now a single newline-separated label, which is easier to generate.
* Booleans display a check mark instead of text, like in the inspector.
* Information labels are selectable and have a `labelled-by` relation.
* The error message is allowed to wrap.

Settings, once implemented, can go at the end of this page.

I debated splitting the plugin info into a stack with 'important' vs 'developer-oriented' entries (somewhat how `GtkAboutDialog` splits its information), but that can go in a separate review if it's done.

NOTE: This deletes the `expanded` property from `GPluginGtkPluginRow`; that's probably an ABI break, though /r/1834 means it was never registered in a released version.

Testing Done:
Opened the separate page of a few plugins, and saw that details were available. Also, the switch was in sync with the switch in the overview.
