In the `examples/platform_view` example, which demonstrates
transitioning from a Flutter view to a general iOS UIView and back, as
well as using channels to communicate between the two, the Flutter view
renders correctly, but in the iOS UIView, the FAB equivalent button in
the lower-right corner is rendered without the '+' icon. This is because
no binding as declared for the add icon in the storyboard. This adds the
missing binding.
Further, this eliminates the use of the deprecated
[UIButtonTypeRoundedRect](https://developer.apple.com/documentation/uikit/uibuttontype/uibuttontyperoundedrect?language=objc),
falling back to the default instead.

* Update project.pbxproj files to say Flutter rather than Chromium
Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
* Update the copyright notice checker to require a standard notice on all files
* Update copyrights on Dart files. (This was a mechanical commit.)
* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).
* Clean up the copyrights in non-Dart files. (Manual edits.)
Also, make sure templates don't have copyrights.
* Fix some more ORGANIZATIONNAMEs
