window: Warn about development builds

With this commit, a message dialog pops up whenever a
development build runs. This is meant to actually annoy,
so that we're always reminded that things may not work
as expected.

Since the dialog can be dismissed with a single button
press, it is not the end of the world. But people still
should be aware that Settings is ~not~ meant to run with
Flatpak, and that this is a development tool only.
