Let Buildship create new settings files when importing

These settings files currently are generated with an initial timestamp
comment line, which is not something we'd want to track in version
control.  Fortunately, the contents of these files are entirely
mundane, so there should be no problem with having Buildship generate
them anew each time a developer imports WALA into Eclipse as an
existing Gradle project.
