Subject: gui: show the real version in About, add the website link

The About dialog had "v1.1.0" hardcoded and no home for the release
version, so it drifted. Add a single BITFLASH_VERSION_STRING in
headers_core.h (bumped at release, unrelated to the protocol nVersion
fields) and show it in About -- now v1.2.20.

Fill the empty line under the version with a clickable
https://bitflash.network that opens in the browser (ShellExecute on
Windows, xdg-open elsewhere), and grow the dialog to fit it.
