The UI workflow:
- user selects the new "Create project from existingsample" radio button
- user selects an SDK target in the NPW
- a popup is filled with all available samples
This also fixes 2 edge cases:
- when the selected sample contains a build|default.propertie that is
a base of the currently selected SDK target, don't reset it.
- when the user manually changes the project name or the app name for
the sample, simply empty the fields and the next selected sample
will recompute the adequate names. Any non-empty user input is never
overridden.
