Update to gtk-rs 0.14, and use bind mappings

[ids1024]

Now "Show Dock on Display" and "Date & Time Notifications Position" show changes in response to changes from gsettings (for instance, dconf-editor). Otherwise behavior should be the same.

This changes Cargo.toml to use the "gtk-rs-0.14" branches of gtk-extras and theme-switcher. That should be changed back to master when those are merged.

Requires pop-os/theme-switcher#24 and pop-os/gtk-extras#3.

While testing this, I had a crash upon turning off Show Minimize Button for the first time (after toggling every setting before it on the page, from top to bottom); however, I was not running G-C-C from a terminal, and when I tried to recreate to see if there's any output, I'm having trouble getting it to happen again. This is the only mention of gnome-control-center in journalctl:

Aug 19 15:29:11 pop-os gnome-shell[2284]: Some code accessed the property 'ext' on the module 'extension'. That property was defined with 'let' or 'const' inside the module. This was previously supported, but is not correct according to the ES6 standard. Any symbols to be exported from a module must be defined with 'var'. The property access will work as previously for the time being, but please fix your code anyway.

Weird. Don't see any issue here toggling both minimize and maximize a bunch of times.

It's hard to diagnose a segfault like that without running in a debugger and getting a backtrace.

[jacobgkau]

I haven't been able to recreate the segfault, so I'll have to assume it was caused by something else and disregard it.

All desktop-widget options still work with this update.
