Not worth splitting all this polish into separate commits, I think...

1. Add frames for other device types
2. Reorganise menus including burger menu
3. Highlight button after upload to show where file is accessible
4. Fix cropped device frame images, scrolling
5. Improve device menu
6. Add Keyman Developer logo and watermark
7. Add status box with current keyboard, model and device
8. Cleanup z-indexing
9. Add About dialog
10. Add Help links
11. Report version in About dialog, title on logo hover
12. Ensure keyboard reloads after change
13. Support loading models over https

- Add separators
- Refactor for clearer win32 delineation
- Add items to open browser

Also, fix minor issues in tray icon - focus, separators in menus

This also tidies up the mkver.sh script and adds the
replaceVersionStrings() function to build-utils.sh for use globally.

1. Renamed form UfrmNGrokOptions to UfrmServerOptions
2. Renamed kmdev-server to just plain server
3. Tidied up npm versioning to use VERSION_WITH_TAG

This last point should help avoid confusion as now only CI release
builds will ever generate a package.json with a.b.c, a.b.c-alpha or
a.b.c-beta. Local and test builds will always have the corresponding
-test or -local environment appended. This also helps avoid issues if
we accidentally publish an incorrect version.

Initial commit for Keyman Developer Server, running on Node.

Supports web debugger only at this point.

Extensive rewrite of web debugger, much of it more modern standards,
significantly improved UX:

1. Drop keyboards, packages, fonts, models onto debug page to load them
2. Websocket for instant reload of recompiled keyboards, packages,
   models.
3. API for interacting with debug server.
4. Cache of recently used items.
5. Integration with ngrok for public access as desired.
6. Tray icon (currently default icon) for control of server.
7. Server can live after TIKE closes, supports multiple TIKE instances.
8. UI of debug host page rewritten with Bootstrap.
9. Packages downloads integrated into main page, and download link for
   Keyman supports all platforms (Linux is just a link to
   instructions...)
10. Avoids file locking and contention by managing all files internally.
11. Not yet tested, but should run cross-platform.

docs(windows): Add note on split user/admin accounts

Adds ngrok configuration dialog and processes for downloading, updating
and setting up ngrok.

It is likely this will change with a refactor of the web debugger into a
standalone node module in the future. This will add support for multi-
instance Keyman Developer and be another step towards a cross-platform
IDE.

If the computer has split user/admin accounts, then language association may not be completed automatically, and the user may need to add a language association themselves.

Note: the topic `configure-computer` has a terrible url but I won't fix that here. Suggested future fix -- turn `configure-computer` into a redirect to `link-keyboard-to-language` or `associate-keyboard-with-language`?
